Practice

Find the vertex and intercepts of the following quadratics. Use this information to graph the quadratic.

1. \(y=x^{2}-2 x-8\)

3. \(y=2 x^{2}-12 x+10\)

5. \(y=-2 x^{2}+12 x-18\)

7. \(y=-3 x^{2}+24 x-45\)

9. \(y=-x^{2}+4 x+5\)

11. \(y=-x^{2}+6 x-5\)

13. \(y=-2 x^{2}+16 x-24\)

15. \(y=3 x^{2}+12 x+9\)

17. \(y=5 x^{2}-40 x+75\)

19. \(y=-5 x^{2}-60 x-175\)
