Let `f:{2,3,4,5} to {3,4,5,9}and g:{3,4,5,9} to {7,11,15}` be functions defined as `f(2)=3,f(3)=4, f(4)=f(5)=5, g(3)=g(4)=7, " and " g(5)=g(9)=11. " Find " gof.`

Explanation

To find the composition of the functions \( g \) and \( f \), denoted as \( g \circ f \), we will evaluate \( g(f(x)) \) for each element in the domain of \( f \).

### Step-by-Step Solution:

1. **Identify the Functions**:
- The function \( f \) is defined as:
- \( f(2) = 3 \)
- \( f(3) = 4 \)
