For the quadratic function (x) = a(x - h) 2 + k, in what quadrant is the

For the quadratic function ƒ(x) = a(x - h)² + k, in what quadrant is the vertex if the values of h and k are as follows?

(a) h> 0, k>0 (c) h<0, k>0 (b) h> 0, k<0 (d) h<0, k<0 Consider the value of a, and make the correct choice. (e) If a > 0, then the graph opens (up / down). (f) If a < 0, then the graph opens (up/down). (g) If a > 1, then the graph is (narrower / wider) than the graph of f(x) = x². (h) If 0 < |a| < 1, then the graph is (narrower / wider) than the graph of f(x) = x².
