Question

1 - In a word math problem what do the following words mean: is, of, sum, product.

2 - What is the process for solving for a function's inverse?

Answer 1

Explanation:

Sum means addition basicaly adding two or more numbers together

Product is when you multiply or times numbers together

First, replace f(x) with y

Replace every x with a y and replace every y with an x .

Solve the equation from Step 2 for y

Replace y with f−1(x) f − 1 ( x )

Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
