Question

Convert the equation from vertex form to standard form y = −4 (x+5)^2 − 3.(1 point)
Responses

y=−4x2−40x−103

y equals negative 4 x squared minus 40 x minus 103

y=16x2+160x+397

y equals 16 x squared plus 160 x plus 397

y=16x2+160x+412

y equals 16 x squared plus 160 x plus 412

y=−4x2−25x−3

y equals negative 4 x squared minus 25 x minus 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.
