Question

(50 points) Which graph is defined by the function given below?

y = (x - 3)(x - 3)
A. Graph A
B. Graph B
C. Graph C
D. Graph D

Answer 1

Graph B

Explanation:

y = (x - 3)(x - 3)

The x intercepts are at 3

Since both intercepts are at 3, the vertex is at 3

We know it is an upwards facing parabola since it is quadratic and the constant out front is positive
