a) Draw graph of quadratic function. Find vertex and intercept(s)
1) f(x) = (x-4)2 - 4
2) f(x) = 30 + 23x + 3x2
b) Write standard form of quadratic function which has indicated vertex and whose graph passes though given point. verify the result with the graphing utility.
Vertex: (-1/4, 3/2) and Point: (-2, 0)
