WebA function f has an inverse function f − 1, iff f is bijective. Let f: A → B, such that f ( x) = y, with x ∈ A, y ∈ B. Then its inverse is a function such that f − 1 maps from the codomain of f to the domain of f, this is: f − 1: B → A So, ∀ y ∈ B, f − 1 ( y) = x, with x ∈ A. Alternatively, By definition of inverse mapping: f − 1 ( y) = x Webf (x) = 1 7 x2 f ( x) = 1 7 x 2. Find the properties of the given parabola. Tap for more steps... Direction: Opens Up.

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. WebDivide f-2, the coefficient of the x term, by 2 to get \frac{f}{2}-1. Then add the square of \frac{f}{2}-1 to both sides of the equation.
