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.

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.
