Answer 1

To determine how many points the functions \( f(x) \) and \( g(x) \) intersect, we need to identify the values of \( x \) where \( f(x) = g(x) \).

Looking at the values provided in the table:

- For \( x = -2 \): \( f(-2) = -7 \) and \( g(-2) = -1 \) (not equal)
- For \( x = -1 \): \( f(-1) = 0 \) and \( g(-1) = 0 \) (equal)
- For \( x = 0 \): \( f(0) = 1 \) and \( g(0) = 1 \) (equal)
- For \( x = 1 \): \( f(1) = 2 \) and \( g(1) = 2 \) (equal)
- For \( x = 2 \): \( f(2) = 9 \) and \( g(2) = 3 \) (not equal)

From this analysis, we see that \( f(x) \) and \( g(x) \) intersect at the following points:
- \( x = -1 \)
- \( x = 0 \)
- \( x = 1 \)

Thus, the functions intersect at **3 points**.

The correct response is:
**3**
