Question

Convert the equation from vertex form to standard form y = -4 (x + 5)^2 - 3. (1 point)
y=-4x^2 -40х - 103
y= 16x^2 +160x + 412
y= 16x^2 + 160х + 397
y=-4х^2 -25х -3

Answer 1

y = -4(x + 5)^2 - 3
= -4(x^2 + 10x + 25) - 3
= -4x^2 - 40x - 100 - 3
= -4x^2 - 40x - 103

So the correct choice is: y = -4x^2 - 40x - 103.
