Question

Let f(x) = 2x - 6 Solve f-1(x) when x = 2.

-5

4

-2

7

Answer 1

f-1(x)
f-1(2)

Answer 2

multiply each term by -1 inside the ( )

Answer 3

Is the f-1(x) supposed to look like this?

\[f ^{-1}(x)\]

Answer 4

multiply -1 by 2
f-1(2)
multiply -1 by 2 and get -2
f-2

Answer 5

yes it is jb1515g

Answer 6

Then you have to find the inverse function first, then plug in x = 2.

Set f(x) = y = 2x - 6.

Solve for x, then swap x and y. That is your inverse function. Then, simply plug in your x into the new equation, and solve.

Answer 7

so it would b -2 then did i get that rt?

Answer 8

Yes, that's what I got when I did it.
