Question

PLS HELP!!!
If f(x) = 5x – 6, what is the equation for f–1(x)?

Answer 1

@Vocaloid

Answer 2

Uh basically find the inverse of the equation, do you know how to do that?

Answer 3

no

Answer 4

\(f(x) = 5x – 6\)
Change f(x) with y to make it easier to look at

\(y=5x-6\)

Now flip x and y and solve for y
\(x=5y-6\)

Answer 5

I think you add 6 or 5 next to both sides?

Answer 6

Add 6, the 5 is being multiplied by y

Answer 7

x=11

Answer 8

x=55

Answer 9

Wait what, you're not supposed to get an answer like that

Add 6 on both sides
\(x+6=5y\)
Then divide by 5 on both sides
\(\large \frac{x+6}{5}=y\)

That is your equation

Answer 10

oh

Answer 11

thanks
