Graphing Parabolas in Vertex Form

If given the equation
y = 3(x + 5)² - 4,
what is the vertex of the parabola?

• (5, -4)

• (-5, -4)

• (-15, -4)

• (15, -4)

Identify the vertex and whether the graph opens up or down.

• (5, 2); opens up

• (5, 2); opens down

• (-5, 2); opens up

• (-5, 2); opens down

What is the vertex of the parabola: y=2(x-3)²+4

• (3,4)

• (-3,4)

• (3, -4)

• (-3,-4)

Using the equation describe the parabola.

• shrink, right by 2, up 3

• shrink, left by 2, up 3

• stretch, right by 2, up 3

• stretch, left by 2, up 3

Match the description to its equation.
