Standard Form, Vertex Form, and Intercept Form of Quadratics

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

• up

• down

• left

• right

Which equation is the vertex form of a quadratic function?

• f(x) = mx + b

• f(x) = a(x - m)(x - n)

• f(x) = ax² + bx + c

• f(x) = a(x - h)² + k

What point contains the minimum or maximum value of a parabola?

• axis of symmetry

• vertex

• roots

• y-intercept

Which equation is the intercept form of a quadratic function?

• f(x) = mx + b

• f(x) = a(x - p)(x -q)

• f(x) = ax² + bx + c

• f(x) = a(x - h)² + k

How many zeros does this parabola have? 

• 3

• 2

• 0

• 1

What is the arrow pointing at? How can you use this value?

• The arrow is pointing at the y-intercept. The x-value is the axis of symmetry and the y-value of this point is equivalent to the maximum/minimum 

• The arrow is pointing at the vertex. The x value of this point is equivalent to the maximum/minimum and the y-value is the axis of symmetry

• The arrow is pointing at the solution. The y value of this point is equivalent to the maximum and the x value is equivalent to the minimum

• The arrow is pointing at the vertex. The x-value is the axis of symmetry and the y-value is equivalent to the minimum/maximum

How many solutions does this graph have?

• one

• two

• no solutions

• cannot be determined

Is this a max or min?

• max

• min

• cannot be determined
