Which equation matches the function described in the table?
Responses

A y = 4xy = 4x

B y = x - 1y = x - 1

C y = x + 5y = x + 5

D y = 4x - 1

Answer 1

The correct answer is D) y = 4x - 1

If you plug the x-values from the table into the equation y = 4x - 1, you will get the corresponding y-values:

When x = 0, y = 4(0) - 1 = -1
When x = 1, y = 4(1) - 1 = 3
When x = 2, y = 4(2) - 1 = 7
When x = 3, y = 4(3) - 1 = 11
When x = 4, y = 4(4) - 1 = 15

Therefore, the equation y = 4x - 1 matches the function described in the table.
