If f(x) = 2x + 2 and g(x) = x? , what is (gºf)(2)?

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

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585
