Answer 5

That is not how we find inverses.

Answer 6

ok can you tell me how then. thanks

Answer 7

f(x) = ax + b

What is the inverse of this?

Answer 8

Try.

Let a and b be constants.

Answer 9

so like this (x-1)

Answer 10

Steps to find inverse of any function f(x):

1) Write x in terms of f(x).
2) Switch all f(x) with x and all x with f(x).
3) The new f(x) is the inverse of the original function.

Example:

f(x) = ax + b

1) Write x in terms of f(x).

\(x = \frac{f(x) - b}{a}\)

2) Switch all f(x) with x and all x with f(x).

\(f(x) = \frac{x - b}{a}\)

3) The new f(x) is the inverse of the original function.

\(f(x) = \frac{x - b}{a}\) is the new inverse.

Answer 11

so A is what im thinkg
