Find the domain and range of the function `f(x)=(1)/sqrt(x5)` f (x) = 1/√x−5 Now for real value of x5≠0 and x5>0 ⇒ x≠5 and x>5 Hence the domain of f = (5, ∞) And the range of a function consists of all the second elements of all the ordered pairs, ie, f(x), so we have to find the values of f(x) to get the required range Now we know for this function x5>0 taking square root on bothQuestion Given the functions f (x) = square root x, and g (x) = (x 5) / (2x 1), find the domain and range of fg (x) composite function Answer domain of fg (x) composite function x is an element of R, x < 05, x is greater or equal to 5 Answer range of fg (x) composite function fg (x) is an element of R, fg (x) is between 0 and
Domain {xl x≠0} Range 1,1 or just 1 and 1, In f(x), all y values are either 1 or 1 The range contains no verticle y values greater than or less than 1 and 1 So maybe I should write this range as {yl y = 1 and 1} or 1U1? The range is the set of all valid values Find the domain and range of f (x)=x2/1x2 Domain of the function is where the function is defined The given function X R Let fx y y x1x2 x y1 x2 yx2 x y 0 This is quadratic equation with real roots Find the domain and range ƒx 1 x2 Maintain the following steps 1When the given function is of the form f(x) = 2x 5 of f(x) = x 2 – 2, the domain will be "the set of all real numbers When the given function is of the form f(x) = 1/(x – 1), the domain will be the set of all real numbers except 1 In some cases, the interval be specified along with the function such as f(x) = 3x 4, 2 < x < 12
Solution for 1 find the domain and range of f(x) 2 cos3xAnswer and Explanation 1 Given f(x) = 1 x f ( x) = 1 x Domain Since the function is a fraction, the value of the variable are all real numbers except 0 0 since it will result to an undefined 2x 1 = 0 2x = 1 x = 1 / 2 Therefore , Domain = R { 1/2 } All real numbers are used as range here For getting solve the denominator of the given fraction and reduce the value of x from the real number "R" Hope it helps you dude
Answer to Consider F(x, y) = 1/(x^2 y^2) Find the domain, the range, and the x and y intercepts By signing up, you'll get thousands of (a) Show that f is onetoone (b) To find (f 1) ' (a) (c) Calculate f 1 (x) and state the domain and range of f 1 (d) Calculate (f 1) ' (a) from the formula in part (c) and check that it agrees with the result of part (b) (e) Sketch the graphs of f and f 1 on the same axes f (x) = xWere given a function and we're asked to find the domain and range of dysfunction Function is F of X equals one plus X square Notice that the function F is a polynomial function that's a quadratic function and therefore the domain of F is all real numbers
Algebra Find the Domain and Range f (x)=1/ (x1) f (x) = 1 x − 1 f ( x) = 1 x 1 Set the denominator in 1 x−1 1 x 1 equal to 0 0 to find where the expression is undefined x−1 = 0 x 1 = 0 Add 1 1 to both sides of the equation x = 1 x = 1 The domain is all values of xExample 1 Find the domain and range of the function y = 3 x 2 Graph the function on a coordinate plane The graph is nothing but the graph y = 3 x translated 2 units to the left The function is defined for all real numbers So, the domain of the function is set of real numbersSo, Domain (f) = x ∈ R Range of ( f ) We know that ∣ x ∣ is always positive So, if a positive quantity is being subtracted from 1 then for all other values of ∣ x − 2 ∣ except 0 , 1 y will be negative and maximum value will be when ∣ x − 2 ∣ = 0 then y = 1
Rule The domain of a function on a graph is the set of all possible values of x on the xaxis For domain, we have to find where the x value starts and where the x value ends ie, the part of xaxis where f(x) is definedFirst week only $499!Answer f (x) = x−5 For f (x) to be defined, the term under the Squareroot should be greater than or equal to zero x−5 ≥0 x ≥ 5 So, the domain is 5,∞)
Find domain and range from graphs Another way to identify the domain and range of functions is by using graphs Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x axis The range is the set of possible output values, which are shown on the y axisSet the denominator equal to zero Remember, dividing by 0 is undefined So if we find values of x that make the denominator zero, then we must exclude them from the domain Now to find the range, notice thatThe domain is all real numbers, and the range is all real numbers f(x) such that f(x) ≤ 4 You can check that the vertex is indeed at (1, 4) Since a quadratic function has two mirror image halves, the line of reflection has to be in the middle of two points with the same y value
Best answer Given that f (x) = 1/√ (x 5) Here, it is clear that (x) is real when x – 5 > 0 ⇒ x > 5 Hence, the domain = (5, ∞) Now to find the range put For x ∈ (5, ∞), y ∈ R Hence, the range of f = R Please log in or register to add a commentSo, the domain of the function f(x) is (∞,∞) Now to find the range, say f(x)= y, which gives x²9=y² or, x= ±√(y²9) Since x is a real number, y²9 must be positive or, y²>9 which gives y ∈ (3,∞),since y>0, which is the required range of f(x)Clearly f(x) = x 1 is defined for all real x, therefore domain of f = D(f) = R (the set of real numbers) Further as f(x) >/= 0 for all x € D(f) = R ,therefore range of f = set of all non negative real numbers
Domain and range The domain and range of a function is all the possible values of the independent variable, x, for which y is defined The range of a function is all the possible values of the dependent variable y The example below shows two different ways that a function can be represented as a function table, and as a set of coordinates
