which of the following ordered pairs is a solution for y=-4x^2
a.(-2,16)
b. (1,-8)
c.(0,-4
) d.(2,-6)
I will test it for b)
Is (1,-8) a solution for y=-4x^2 ?
LS = -8
RS = -4(1^2) = -4 , nope (1,-8) does not work in y=-4x^2
etc until you find the correct choice

it was only on pay-per-view...
ba da bing!
To determine which of the given ordered pairs is a solution for the equation y = -4x^2, we need to substitute the x and y values into the equation and check if the equation is satisfied.
Let's go through each of the options:
a. (-2, 16):
Substituting x = -2 and y = 16 into the equation:
16 = -4(-2)^2
16 = -4(4)
16 = -16
The equation is not satisfied, so this ordered pair is not a solution.
b. (1, -8):
Substituting x = 1 and y = -8 into the equation:
-8 = -4(1)^2
-8 = -4(1)
-8 = -4
The equation is not satisfied, so this ordered pair is not a solution.
c. (0, -4):
Substituting x = 0 and y = -4 into the equation:
-4 = -4(0)^2
-4 = -4(0)
-4 = 0
The equation is not satisfied, so this ordered pair is not a solution.
d. (2, -6):
Substituting x = 2 and y = -6 into the equation:
-6 = -4(2)^2
-6 = -4(4)
-6 = -16
The equation is not satisfied, so this ordered pair is not a solution.
Based on our analysis, none of the given ordered pairs (a, b, c, or d) satisfy the equation y = -4x^2. Hence, there is no solution among the given options.
