11. 4. Which of the following pairs of functions would be an example of a Non Quadratic F(X) and a Quadratic G(X)? A.f(x) = x 2 - 7x and g(x) = x 3 + 4x 2 B. f(x) = 8 -3x and g(x) = 2x 3 + 6x 2 C.f(x) = 36 and g(x) =-5x + 2 D.f(x) = x 2 + 3/(x 2) and g(x) = 15 + 4x 2

12. 4 f(x) = x 2 + 3/(x 2) and g(x) = 15 + 4x 2

13. 5 The point (4,7) lies on the graph of the equation y = x 2 + c. Find the value of c.

14. 5 C=9

15. 6 Describe how the value of c in the quadratic function 0 = ax 2 + c affects the shape of the parent graph y = x 2 ?

16. 6 Shifts up +C

17. 7 A Quadratic Graph has all of the following except which one? It has a parabola It has symmetry It has a vertex It has a constant rate of change It has a minimum and maximum

18. 7 It has a constant rate of change It has a minimum and maximum

19. 8 The Banner store offers several sizes of rectangular Banners for businesses to hang by their cash registers. All sizes have a length (l) 4 inches more than its width (W). If W represents the width of the banner and W+4 represents the length then the area of the banners can be represented by the equation W(W+4)=A or W^2 +4w, Create a table to represent the W and the Area if the widths are 1, 3, 6, 9

20. 8 Solutions may vary

21. 9 Describe how A B and C in the equation Ax^2 +bx+c affect the graph.

22. 9 If a is positive, a is negative? What does B do? C is translations? What about dilations?
