Question

y=-2x^(2)+4x-6
Responses: y=1, x=1, x=3, x=-3

Answer 1

1. When x = 1:
y = -2(1)^2 + 4(1) - 6
y = -2 + 4 - 6
y = 2 - 6
y = -4

Therefore, when x = 1, y = -4.

2. When x = 3:
y = -2(3)^2 + 4(3) - 6
y = -2(9) + 12 - 6
y = -18 + 12 - 6
y = -6

Therefore, when x = 3, y = -6.

3. When x = -3:
y = -2(-3)^2 + 4(-3) - 6
y = -2(9) - 12 - 6
y = -18 - 12 - 6
y = -36

Therefore, when x = -3, y = -36.
