Graphing Quadratics

What are the green dots called?

• axis of symmetry

• vertices

• maximum and minimum

• roots or x-intercepts

Which is standard form of a quadratic equation?

• y=x²

• y=ax²+bx+c

• y=mx+b

• y=a(x-h)²+k

• Ax + By =C

Does this parabola have a minimum or maximum and what is its value?

• minimum: 2

• maximum: 2

• minimum: 5

• maximum: 5

What are the x- intercepts?

• x= 0 and x= -4

• x= 0 and x= 4

• y= 0

• x= 2

A parabola is upside-down when a is:

• negative
• positive
• 0
• infinite

What is another word for zeros?

• y-intercepts

• x-intercepts

• vertex

• axis of symmetry

True or false:
The solutions, roots, x-intercepts, and zeros of a quadratic equation 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

In the equation

y = x² +5x +7, match each leading coefficient with its correct letter

• a=0, b=5, c=7

• a=1, b=5, c=7

• a=7, b=5, c=1

For the quadratic parent function, f(x) = x², the vertex is always:

• (0, 0)

• (0, 1)

• (1, 0)

• undetermined

When comparing the graph of g(x) = 4x² to the parent function f(x) = x², the graph of g(x) is:

• a vertical shrink (wider)

• a vertical stretch (narrower)

• a reflection

• 4 times as wide
