Which function in vertex form is equivalent to f(x) = x2 + 8 – 16x?
A
f(x) = (x – 8)2 – 56B
f(x) = (x – 4)2 + 0C
f(x) = (x + 8)2 – 72D
f(x) = (x + 4)2 – 325
Which function in vertex form is equivalent to f(x) = 4 + x2 – 2x?
A
f(x) = (x – 1)2 + 3B
f(x) = (x – 1)2 + 5C
f(x) = (x + 1)2 + 3D
f(x) = (x + 1)2 + 5Did you find these answers helpful?
