Question

Can anyone help me out. f(x)=1over 8x+9.
Thanks!

Answer 1

What exactly are you suppose to do with the function?

Answer 2

Find the inverse of the function. Here are the possible solutions: A) f-1(x)=8x+72 B) f-1(x)=1over8x-9 C) f-1(x)=1 over 9x+8 D) f-1(x)=8x-72

Answer 3

I'm stumped.
Is this what you're trying to do?

Answer 4

Is it \[f(x) = [1/8x]+9\]
OR
\[f(x) = 1/(8x+9)\]

There's a difference when solving both.

Answer 5

PS. The first of Veronometry's equations will give you a match. Follow the steps in the link above.

Answer 6

thank your. I will

Answer 7

I would be X is an element of (-infinite, -9/8) or (-9/8, infinite) Because you set the bottom, Underneath the bar, to equal zero...

Because division of 0 is undefined. Then what ever your answer is is the one thing that X cannot be.
