2) 14

3) 18

4) 21

Answer 1

\[\large f(x) = x - \frac{5}{3}\]

right?

Answer 2

Given f(x) =x-5/3 , solve for f^-1(3). (5 points)
Question 2 options:

1) -1

2) 14

3) 18

4) 21

Answer 3

its to the -1 power I wrote it wrong

Answer 4

I got what you meant though, but I'm making sure the f(x) equation is correct for now

Is it all over 3...or is it as I have written above?

Answer 5

(x-5)/3 @johnweldon1993

Answer 6

Let
f(x)=y

Answer 7

So
y=(x-5)/3
3y=x-5
x=3y+5

Answer 8

So
f^-1(y)=3y+5

Answer 9

Tell me
f^-1(x)=?

Answer 10

Just replace y by x
