It can be shown that for the quadratic function f(x)= ax +bx+c, the x-coordinate of -b the parabola's vertex will always be x = 2a For each function below, • Use the vertex formula x = to determine the x-coordinate of the parabola's 2a vertex. (Show your work!) • Evaluate in order to determine the y-coordinate of the vertex. (Show your 2a work!) • Graph f(x) on your calculator to verify that the coordinates of the vertex that you found are correct. 1. f(x)=3x²-12x+7
