Answer to Question #56098 in Algebra for Bobby Bass

Question

8: Which function will produce the same graph as the function shown below?
Y = (x + 1)(x + 3) Multiple answers may be correct.

Y + 3 = x(x-1)

y = x^2 + 4x + 3

y = x^2 + 4x – 3

y – 3 = (x-1)^2

9: What is the equation on the axis of symmetry for the function shown below?
Y – 1 = -2(x + 3)^2 There can be multiple right answers.

x = 3

y = 7

x = -2

x = -3

10: Which point lies on the graph of the function shown below?
Y = -x^2 + 4x – 2

A: (1,1)
B: (2,-2)
C: (-1,3)
D: (0,2)

11: Which function represents a translation of the graph of y = x^2 by 5 units to the left. Multiple answers may be correct check all that apply.

Y = x^2 + 5

Y= (x – 5)^2

Y= 5x^2

Y= (x + 5)^2
