• x=-3

• y= -3

• x=2

• y=2

What is the range for the quadratic graphed?

• All real numbers

What is the domain of the quadratics that is graphed?

What is the reasonable domain of the quadratic graphed?

• all real numbers

• Yes
• No

Does the mapping of these points represent a function? (Note: the left oval represents your x values and the right oval represents your y values)

• Function

• Not a Function

What is true about this function?

• It is Quadratic

  decreasing

  x-intercept: (.25,0)

  y-intercept: (0,-1)

• It is Exponential

  decreasing

  x-intercept: (0,.25)

  y-intercept: (-1,0)

• It is Quadratic

  increasing

  x-intercept: (-.25,0)

  y-intercept: (0,0)

• It is Exponential

  increasing

  x-intercept: (-.25,0)

  y-intercept: (0,-1)

• None of the above

The graph is a picture of both ​ (a)  

• relation

• function

• domain

• range

• x-intercept

• y-intercept

• rate of change

• minimum

• maximum

• extrema

Answer explanation

Extrema are both the highest (maximum) point and the lowest (minimum) points.

What is the definition of function?

• Has inputs and outputs

• Every input has only one output

• Inputs have different outputs every time

• x-values and y-values

What is the reasonable range for the quadratic graphed?

• all real numbers
