Isolate y by adding 4 to both sides:
Divide both sides by 9:
Take the cube root of both sides:

Answer:
and
Step-by-step explanation:
If we want to express as
, this means that put the function
into
of
to get
.
The function is given as
<u>So we need to figure out a function that we can put into another
to get
</u>
If we let and
, we can clearly see that putting g(x) into x of f(x) will give us
, which is y.
Hence and
