Question

Find a formula for the inverse if it exists.

f^-1(x)= ?????
Help!

Answer 1

have to have the form of f(x) first, and then from that find out the f^(-1) if it exists. So, what is f(x)?

Answer 2

Here is the the entire question, f(x)=8x-6 now it wants me to find the formula for the inverse
f-^1(x)=

Answer 3

want to know how to get or just answer?

Answer 4

Both I'm lost and taking a test which I have to pass

Answer 5

I would love it if you showed me how you got the answer that would help with the rest of the questions

Answer 6

so, do what I suggest, ok? replace f(x) =y what do you get?

Answer 7

I don't understand. I'm so lost and MAT 150 has thrown me for a huge loop

Answer 8

where you see f(x) take it out and write y there at the original one

Answer 9

okay so y=8x-6

Answer 10

good, now from y = 8x -6
switch the place of x and y, remember "SWITCH"

Answer 11

x=8y-6?

Answer 12

yes, now plus 6 both sides

Answer 13

6x=8y?

Answer 14

nope, + (plus) not * (time), redo, please

Answer 15

"a plus b" is "a + b"

Answer 16

don't get what I mean?

Answer 17

Not really.
