For f x 2x+1 and g x x2-7 find f/g x
WebTo find the answers, I can either work symbolically (like in the previous example) and then evaluate, or else I can find the values of the functions at x = 2 and then work from there. It's probably simpler in this case to evaluate first, so: f (2) = 2 (2) = 4 g (2) = (2) + 4 = 6 h (2) = 5 − (2) 3 = 5 − 8 = −3 WebSolve your math problems using our free math solver with step-by-step solutions.

WebLet us try doing those operations on f (x) and g (x): Addition We can add two functions: (f+g) (x) = f (x) + g (x) Note: we put the f+g inside () to show they both work on x. Example: f (x) = 2x+3 and g (x) = x 2 (f+g) (x) = (2x+3) + (x 2) = x 2 +2x+3 Sometimes we may need to combine like terms: Example: v (x) = 5x+1, w (x) = 3x-2 WebAug 4, 2016 · =x f(g(x))=2(x-1)/2+1 =x-1+1 =x

Then we have: 𝑔 (𝑥 + 6) = 5𝑥 + 8 The variable we use doesn't matter, so to avoid confusion, we will write this functional equation in 𝑘 instead of 𝑥: 𝑔 (𝑘 + 6) = 5𝑘 + 8 Since 𝑘 ∈ ℝ, we let 𝑘 = 𝑥 – 6 where 𝑥 ∈ ℝ. Thus: 𝑔 (𝑥 – 6 + 6) = 5 (𝑥 – 6) + 8 Which we reduce to: 𝑔 (𝑥) = 5𝑥 – 22

Inverse Function Theorem If y = g (x) is the inverse of f (x), then g' (x) = 1 / f ' (g (x)). Since, f (x) = 3x 3 + 2x + 1, it follows that f ' (x) = 9x 2 + 2. So by the above theorem, g' (1) = 1 / f ' (g (1)) where f ' (g (1)) = 9 · g (1) 2 + 2.
