Math Problem Statement
For f(x) = x - 3 and g(x) = 5x^2 - 3, find the following functions: a) f ∘ g(x).
Solution
The image contains a problem where two functions are given:
We are asked to find the composition of functions , which means we need to evaluate .
Solution for part (a):
- Start with the function for :
- Now substitute into the function , i.e., replace in with :
- Simplify:
Thus, the solution for part (a) is:
