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

• parabola
• vertex
• graph
• point

What is the green dot on the parabola called?

• maximum

Changing the c value of a standard form quadratic (y=ax²+bx+c) transforms the graph how?

• Up and down

• Left or right

• Reflects over x axis

• Up only

• Creates a change in the universe that is so chaotic it creates a new galaxy

The standard form of a quadratic function is

• y = ax² + bx + c

• a(x - h)² + k

• y - y₁ = m(x - x₁)

• Ax + By = C

If a is negative in the quadratic function, which way does the parabola open?

• up

• down

• left

• right

Identify a, b, and c if y = +3x² +5x - 8

• a=3, b=5, c= - 8

• A=3, B=-8, C=5

• A=3x², B=5x, C=-8

• A=3x² , B=-8, C=5x

• Maximum
• Minimum

What do we call the graph of a quadratic?

• line
• vertex
• equation
• parabola
