Quadratic functions in vertex form — Homework
Identify vertex, direction, and width before graphing or evaluating anything.
- 1.Identify the vertex and direction of opening: f(x)=4(x-2)^2-9.
- 2.Evaluate f(x) = -1(x+3)^2 + 10 at x=0.
- 3.Write the vertex form for a parabola with vertex (-2,5), opening downward, narrower than y=x^2 (use a=-3).
- 4.Is the vertex of f(x)=(x+4)^2-6 a minimum or maximum? What is that value?
- 5.How does |a| being greater than 1 versus between 0 and 1 change the width of a parabola?
