Comparing Functions Test

Match the graph to the type of function.

• Green Graph = Linear

  Red Graph = Quadratic

  Blue Graph = Exponential

• Green Graph = Quadratic

  Red Graph = Linear

  Blue Graph = Exponential

• Green Graph = Exponential Red Graph = Linear

  Blue Graph = Quadratic

Identify the type of function. Justify your reason.

• Linear because x increases at a constant rate.

• Quadratic because the y values are squaring each time.

• Exponential because the common ratio is 3.

• Exponential because the common second difference is 3.

• Linear because the degree is 1.

• Exponential because 'x' is being multiplied by a fraction.

• Exponential because the common ratio is 2/3.

• Linear because there is only one variable.
