The image contains the question:

**If \( f(x) = 2x + 3 \), what is \( f(2) \)?**

Let's solve it:

Given the function \( f(x) = 2x + 3 \), we need to calculate \( f(2) \):

\[
f(2) = 2(2) + 3 = 4 + 3 = 7
\]

So, the correct answer is **D) 7**.

Here are five related questions:
1. What is \( f(3) \) if \( f(x) = 2x + 3 \)?
2. What is the slope of the line represented by \( f(x) = 2x + 3 \)?
3. How do you find \( f(x) \) when given an input value for \( x \)?
4. Can you determine the y-intercept from the equation \( f(x) = 2x + 3 \)?
5. What is the difference between linear and nonlinear functions?

**Tip:** A function like \( f(x) = 2x + 3 \) is a linear equation, where the graph is always a straight line.

Learn how to solve a linear function by substituting the given value of x into the function f(x) = 2x + 3. In this case, we solve for f(2) step-by-step, showing the calculation and result. This problem is ideal for middle school students in Grades 6-8.
