F inverse? then :
let's consider 3x + 9 as y.
so :
y = 3x + 9
y - 9 = 3x
x = y/3 - 3
now replace y with x and you get the inverse.
f^-1 (x) = x/3 - 3

Based on this screenshot, this is a Test. Do the test no your own, and if you're unsure what the answer is you can come back to it later or just pick random. If you get it correct or incorrect most tests like this will change their difficulty level to see what types of problems you can and cannot answer. This is so your teacher can see what you know about math and what you may need help learning about.
