Is it even possible to find the inverse of this? *edit* the question is find but to do that I must 1st find

it is possible, but rather pointless for this exercise, you just say

no, you just need to find what value of x gives 6 as an answer, when they say find they are asking what value of x gives 6 as an output for f(x), and you do not need a formula for Just by looking I can see the answer is 4
Yes, x= 4 works. And that is as good a method as any!
