A quadratic function is a function of degree two The graph of a quadratic function is a parabola The general form of a quadratic function is f(x) = ax2 bx c where a, b, and c are real numbers and a ≠ 0 The standard form of a quadratic function is f(x) = a(x − h)2 kExpand the following (2 y x)^5 (2 y x)^5 = sum_(k=0)^5 binomial(5, k) (2 y)^(5 k) x^k = binomial(5, 0) (2 y)^5 x^0 binomial(5, 1) (2 y)^4 x^1 binomialHi Note the use of ^ (uppercase 6 on Your keyboard) y = 3 (x5) (x2)= 3 () = 3x^2 9x 30 (x5) (x2) Using Foil method of multiplying F First terms x^2
