Question

Given f(x) = (x-1)/2, solve for f^-1 (5)

Answer 1

is this a test

Answer 2

@funnyguy2 classwork, I'm just really confused

Answer 3

Hi welcome to openstudy!!

FIRST, set f(x) = y
so your equation will be \(\sf y=\frac{ (x-1)}{2}\)

SECOND, switch the places of x and y since you are looking for the inverse of the function:
you'll have: \(\sf x=\frac{ (y-1)}{2}\)

THIRD, solve the equation in terms of y, can you do this for me ? :)

Answer 4

@Data_LG2 I am a little confused what you mean by that. do you want me to multiply -1 to both sides? So then Ill have x= y/2?

Answer 5

nope, try arranging the equation so that y will be on the left side instead of x

Answer 6

for example:

Answer 7

So I will multiply y to both sides which will give me yx=-1/2 and then I will divide by x?
