Answer:
1)
x y
-3 -8
0 1
2 7
2)
x y
-3 2
0 -2
4 -6
3)
- Each domain is paired with only 1 range
- You could use the vertical line test
Step-by-step explanation:
1) y = 3x + 1
when x = -3; y = 3(-3) + 1 = -9 + 1 = -8
when x = 0; y = 3(0) + 1 = 0 + 1 = 1
when x = 2; y = 3(2) + 1 = 6 + 1 = 7
2) y = -x - 2
when x = -3; y = -(-3) - 2 = 4 - 2 = 2
when x = 0; y = -(0) - 2 = -2
when x = 4; y = -(4) -2 = -4 -2 = - 6
3)
- Each domain is paired with only one range
- You could use the vertical line test
