The formula given is used to find what?

• rate of change

• distance between two points

• intercepts

• vertex

The - 3 in the given equation does what to the parent function?

• vertical shift up 3
• horizontal shift right 3
• vertical shift down 3
• horizontal shift left 3

Choose the equation of the given graph.

• f(x)=(x + 3)(x - 2)²(x + 1)
• f(x)=(x - 3)(x + 2)²(x - 1)
• f(x)=(x + 3)(x + 2)(x - 1)²
• f(x)=(x - 3)²(x + 2)²(x - 1)

What is the vertex of f(x) = -4x² + 16x - 1 ?

• (2, 15)
