Which represents a quadratic function?
*
f(x) = -8x3 - 16x2 - 4x
f(x) = * x2 + 2x - 5
px) = - ] +1
f(x) = 0x² – 9x+7

F(x) = x2 − 9, and g(x) = x − 3 f(x) = x2 − 4x + 3, and g(x) = x − 3 f(x) = x2 + 4x − 5, and g(x) = x − 1 f(x) = x2 − 16, and g(x) = x − 4 h(x) = x + 5 arrowright h(x) = x + 3 arrowright h(x) = x + 4 arrowright h(x) = x − 1 arrowright

How can you tell when x and y are not directly proportional?
