WebQuestion: Find the function value. If f(x)=2x−1x+12, find f(4),f(0), and f(−1) f(4)= (Type an integer or a simplified fraction.) f(0)= (Type an integer or a simplified fraction.) f(−1)= (Type an integer or a simplified fraction.) Show transcribed image text. Expert Answer. WebSee a solution process below: Explanation: Because there are no restrictions on the value x can be, then the domain of the function is the set of Real numbers: {R} ... If f (x) = −2x+ 7 …

for f(x) = -2x + 7, find the value of f(-1) + f(4) - Brainly.com

WebTo find the inverse of a function, swap the x"s and y"s and make y the subject of the formula. Example Find the inverse of f (x) = 2x + 1 Let y = f (x), therefore y = 2x + 1 swap the x"s and y"s: x = 2y + 1 Make y the subject of the formula: 2y = x - 1, so y = ½ (x - 1) Therefore f -1 (x) = ½ (x - 1) WebDec 4, 2024 · In the function as the value of the independent variable varies the value of the dependent variable also varies. Given that the function is f (x) = -2x + 7. The value of the … emily real housewives oc husband

Web(f º f) (x) = f (f (x)) First we apply f, then apply f to that result: (f º f) (x) = 2 (2x+3)+3 = 4x + 9 We should be able to do it without the pretty diagram: (f º f) (x) = f (f (x)) = f (2x+3) = 2 (2x+3)+3 = 4x + 9 Domains It has been easy so far, but now we must consider the Domains of the functions. WebSep 9, 2024 · f −1(x) = ± √x − 4 Note that by the formal definition f −1(x) is not a function, as it is multi-valued. This occurs because squaring either a positive or negative number in the original function yields a positive number: f ( −1) = f (1) = 5 ⇒ f −1(5) = ± 1 Answer link WebAlgebra Graph f (x)=2x-7 f (x) = 2x − 7 f ( x) = 2 x - 7 Rewrite the function as an equation. y = 2x− 7 y = 2 x - 7 Use the slope-intercept form to find the slope and y-intercept.
