Answer:
X | F(x)
-4 | -3
-2 | -1
0 | 1
2 | 3
4 | 5
Step-by-step explanation:
F(x) problems or function problems are input/output questions. You put the X value in for X in F(x) to get an output. In this question a graph is used. In this case the question gives a table, so you can simply find the inputs and outputs based on a pattern.
In the X-values or the input values: -4, -2, 0
You can keep going by two: 2, 4
In the F(x) values or output values: 1, 3, 5
You can't count backwards by two to get: -1, -3
