HW 16.1a - Graphing Quadratic Functions

What do we call the highest or lowest point of a quadratic?

• parabola
• vertex
• graph
• point

What is the vertex?

• (2, 4)
• (3, -1)
• (0, 8)
• (4, 2)

True or false:
The root, x-intercept, and zero are all the same thing

• True
• False, because the solution and root are the same but the x-intercept and zero are different
• False, because the x-intercept and root are the same but the zero and solution are different
• False, they are all different

How many zeros does this parabola have? 

• 3
• 2
• 0
• 1

What is the y-intercept?
f(x) = -2x² + 4x - 6

• (0, 6)
• (0, -6)
• (6, 0)
• (-6, 0)

The U-Shaped graph of a quadratic function  is called a?

• Marabola
• X-value
• Parabola
• Height

The parent function of a quadratic function is?

• y=mx+b
• y=x
• y=x²
• y=-x²

Does y = -4x² have a maximum or minimum value?

• maximum
• minimum

Find the y-intercept of f(x) = 2x²-2x + 1

• 2
• -2
• 1
• -1

Use the graph of the function f(x)=-2x²+4x+6 to find the solution(s) of the equation -2x²+4x+6=0.

• x=-1
• x=3
• x=-1 and x=3
