y=−4x^(2)−25x−3

y equals negative 4 x squared minus 25 x minus 3

y=16x^(2)+160x+397

y equals 16 x squared plus 160 x plus 397

y=−4x^(2)−40x−103

y equals negative 4 x squared minus 40 x minus 103

y=16x^(2)+160x+412

y equals 16 x squared plus 160 x plus 412

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.
