Question

Help I’m so confused

Answer 1

Answer:

y = 3x + 6

Step-by-step explanation:

The domain is you x values. You need to substitute the x values into both functions to see which one produces the plots on the graph.

y = 2x + 4

when x = -3, y = 2(-3) + 4 = -6 + 4 = -2

when x = -2, y = 2(-2) + 4 = = -4 + 4 = 0

when x = -1, y = 2(-1) + 4 = = -2 + 4 = 2

when x = -0, y = 2(0) + 4 = 0 + 4 = 4

y = 3x + 6

when x = -3, y = 3(-3) + 6 = -9 + 6 = -3

when x = -2, y = 3(-2) + 6 = = -6 + 6 = 0

when x = -1, y = 3(-1) + 6 = = -3 + 6 = 3

when x = -0, y = 3(0) + 6 = 0 + 6 = 6

The points on the graph are (-3, -3), (-2, 0), (-1, 3) and (0, 6)

This is same as the results from the function y = 3x + 6
