The problem defines a function $G$ that takes a student's first name as input and returns the number of letters in that name. Part (a) asks for the meaning of $G(\text{Jada}) = 4$. Part (b) asks us to find the value of $G(\text{Diego})$.

1. Problem Description

The problem defines a function $G$ that takes a student's first name as input and returns the number of letters in that name. Part (a) asks for the meaning of $G(\text{Jada}) = 4$. Part (b) asks us to find the value of $G(\text{Diego})$.

2. Solution Steps

a. The expression $G(\text{Jada}) = 4$ means that when the input to the function $G$ is the name "Jada", the output is

4. This means the name "Jada" has 4 letters.

b. We need to find $G(\text{Diego})$. This means we need to count the number of letters in the name "Diego". The letters are D, I, E, G, O. There are 5 letters. Therefore, $G(\text{Diego}) = 5$.

3. Final Answer

a. $G(\text{Jada}) = 4$ means that the name "Jada" has 4 letters.

b. $G(\text{Diego}) = 5$.
