To solve this problem, you must plugin the value f(x) into g(x). This gives you (x^2)-3. That is the simplest form of that expression.
All you have to do is just plug in the values. Look at our composition:
(g(f(x))
simply replace g and f with their corresponding functions. This looks like:
x-3(x^2(x))
This can be re-arranged in to (x^2) -3
