Features of Quadratic Functions

A parabola has a vertex at (-3,2). Where is the axis of symmetry?

• y = -2
• x = 3
• x = -3
• y = 2

What is the vertex of y= x² - 8x + 14 ?

• (2, 4)
• (-4, -2)
• (4, -2)
• (-2, 4)

Find the vertex of the quadratic:
y = -2x² + 4x + 3

• (0, 3)
• (-1, 5)
• (1, 5)
• (1, -5)

Does the equation open up or down? 
Y = -3x² +7x - 2

• up
• down
• Neither; it opens to the right.
• Neither; it opens to the left.

What is the name of this form:
y = ax² + bx + c

• vertex form
• standard form
• factored form
• zero form

What is the maximum/minimum of a parabola called?

• vertex
• point
• top
• bottom

What do we call the graph of a quadratic function?

• parabola
• linear
• cubic
• sinusoidal

Where is the axis of symmetry for this parabola?

• x = −1
• x = 0
• y = 3
• x = −3

What is the formula above primarily used for?

• Finding the axis of symmetry from standard form
• Finding the vertex from standard form
• Finding the vertex from vertex form
• Finding the vertex from standard form

How do you know if a parabola has a minimum?

• When ‘a’ is positive there is a minimum

• When ‘a’ is negative there is a minimum

• When all the numbers in the equation are negative there is a minimum

• When all the numbers in the equation are positive there is a minimum
