Question

x=-2
y=-3/4x^2 what would y be I got -3

Answer 1

That depends. If the x^2 is in the denominator than no, but if the x^2 is not in the denominator than yes. If the x^2 is in the denominator than it would be y = -3/[4(-2)^2] = -3/16

Answer 2

it is in the denominator

Answer 3

Then the answer should be -3/16 because in the denominator you have 4(-2)^2 which is equal to 4(4) or 16
