Question

This table compares the values of functions f(x) and g(x) for different x values.

x f(x) g(x)
-2 -7 -1
-1 0 0
0 1 1
1 2 2
2 9 3

Compare the functions f(x) and g(x). At how many and which points do the functions intersect?

Answer 1

Compare the outputs in the table: f(x)=g(x) at x = -1, 0, and 1. So they intersect at 3 points: (-1, 0), (0, 1), and (1, 2).
