Which equation is y = (x + 3)2 + (x + 4)2 rewritten in vertex form? - answer A.
Which phrase best describes the translation from the graph y = 6x2 to the graph
of y = 6(x + 1)2? - answer C. 1 unit left
Which pair of equations generates graphs with the same vertex? - answer B. y = -
4x2 and y = 4x2
How does the graph of y = a(x - h)2 + k change if the value of h is doubled? -
answer B. The vertex of the graph moves to a point twice as far from the y-axis.
Which equation has a graph that is a parabola with a vertex at (5, 3)? - answer A.
