Question

Given the function f(x) = 4(x+3) − 5, solve for the inverse function when x = 3.

−21

−16

−10

−1

Answer 1

replace f(x) with y, and exchange variables
4(x+3) − 5 = y
4(y+3) - 5 = x

Answer 2

solve for y

Answer 3

which choice? sorry to bother

Answer 4

dunno, do the math.

Solve for y \[\huge 4(y+3) - 5 = x\]

Answer 5

- 21 -16 -10 or -1

Answer 6

ill give you a medal right now

Answer 7

I don't want a medal. I got more medals than I can ever use

Answer 8

Answer 12

I got a different answer

Answer 13

u sure its right lol

Answer 14

add 5 to 12 is what i did

Answer 15

I added 5 to both sides of \[\huge 4(y+3) - 5 = x\]and got\[\huge 4(y+3) = x + 5\]

Answer 16

Bib you're too good :"D

Answer 17

the answer would be the solution to f(x) = 3
