Y = a(x h) 2 Vertex Form k k vertical translation 'k' units k > 0 , the graph is translated 'k' units up k< 0 , the graph is translated 'k' units down y = x 2 4 y = x 2Correct answers 2 question Finish the steps below to write a quadratic function for the parabola shown 4 Use the vertex form, f(x) = a(x h)2 k, and substitute in the values for h and ke f(x) = a(x – 5)2 3 2 Use another point and substitute in values for x and f(x) Solve for a 5 = a(6 – 5)2 3 3 Write the function, using the values for h, k, and a The function is f(x) = Tx 12All quadratic functions include a term that contains the square of the independent variable, like x 2 There can be no higher power of x in a quadratic function Some examples are f ( x) = 2 x 2 − 3 x 1 f ( x) = ( x − 4) 2 f ( x) = − x 2 − 71 Quadratic functions have the general form
