Graphing Parabolas in Vertex Form Practice

Front

What is the vertex of the parabola represented by the equation y = (x + 3)² + 5?

Back

(-3, 5)

Front

What is the vertex of the graph represented by the equation y = (x - 2)² + 4?

Back

(2, 4)

Front

A parabola has a vertex at (4, -1). Where is the axis of symmetry?

Back

x = 4

Front

What is the axis of symmetry for the parabola represented by the equation y = x²?

Back

x = 0

Front

Identify the vertex and whether the graph opens up or down for the equation y = (x + 5)² + 2.

Back

(-5, 2); opens up

Front

What is the standard form of a parabola?

Back

y = a(x - h)² + k, where (h, k) is the vertex.

Front

How do you determine if a parabola opens up or down?

Back

If 'a' in y = a(x - h)² + k is positive, it opens up; if negative, it opens down.

What is the vertex of the parabola y = -2(x - 1)² + 3?

Back

(1, 3)

Front

What is the axis of symmetry for the parabola y = 3(x + 2)² - 1?

Back

x = -2

Front

Identify the vertex and direction of opening for y = -4(x - 3)² + 1.

Back

(3, 1); opens down
