Question

Given f(x) = the quantity of 2x minus 2 divided by 4, solve for f−1(3).

Answer 1

Dude spongebob looks awful

Answer 2

correction: sexy

Answer 3

\[f(x)=\frac{ 2x-2 }{ 4 }\]

Answer 4

except needs to be inverse

Answer 5

find the inverse of f(x) first
f(x)=(2x-2)/4
y=(2x-2)/4
solve for x we get
4y=2x-2
4y+2=2x
(4y+2)/2=x
replace x and y we get its inverse
(4x+2)/2= y
f-1(x)=(4x+2)/2
f-1(3)=??
sub 3 where x is to solve...

Answer 6

@LynFran So it's f(3) = 7?

Answer 7

yep

Answer 8

okie thnx! :D
