I have displayed the image. Let me extract the exercises from the image and solve them for you.

The exercises are:

1. $f(x) = 2x + 3$ for $x = 2$
2. $f(x) = 2x - 7$ for $x = 2$

Let's solve them step by step:

1. For $f(x) = 2x + 3$ and $x = 2$: $f(2) = 2(2) + 3 = 4 + 3 = 7$

2. For $f(x) = 2x - 7$ and $x = 2$: $f(2) = 2(2) - 7 = 4 - 7 = -3$

Would you like more details, or do you have any questions?

Here are 5 related questions:

1. How do you evaluate a function for different values of $x$?
2. What is the significance of substituting values into functions?
3. Can you find $f(x)$ if $f(x) = 3x^2 + 2x - 1$ and $x = 3$?
4. How does function evaluation apply in real-world situations?
5. What happens if the function includes fractions or higher powers?

Tip: Always double-check your calculations, especially with negative numbers!
