Question

Choose the correct set of y-values for the function y = 2x when x = -2, 0, 2.

a) A(-2, 4), (0, -2), (2, 4)
b) B(-2, -4), (0, 0), (2, -4)
c) C(-2, 4), (0, 0), (2, -4)
d) D(-2, -4), (0, 0), (2, 4)

Answer 1

The correct set of y-values for the function y = 2x when x = -2, 0, 2 is option D: (-2, -4), (0, 0), (2, 4).

Step-by-step explanation:

The student has asked for the correct set of y-values for the function y = 2x when x = -2, 0, 2. To find the y-values, we simply substitute the given x-values into the function and calculate:

• When x = -2: y = 2(-2) = -4
• When x = 0: y = 2(0) = 0
• When x = 2: y = 2(2) = 4

Thus, the correct set of y-values corresponds to option D, which is (-2, -4), (0, 0), (2, 4).
