Connecting Representations of Functions

Function A is represented by the equation. Function B is represented by the graph. What is the rate of change of Function A?

• 5

• 3/2

• 2/3

• 0, 5

Function A is represented by the equation. Function B is represented by the graph. What is the rate of change of Function B?

• 0, 1

• 3/2

• 2/3

• 0, -1

Function A is represented by the equation. Function B is represented by the graph. Which function has the greater rate of change?

• Function A

• Function B

Which function has the greater rate of change?

• Function A because 4/3 is greater than 2.

• Function B because 1/2 is greater than 1/4.

• Function A because 4 is greater than 2.

• Neither. They both have a rate of change equal to 4.

Valerie and Oscar are contestants on the Biggest Loser. Valerie's weight loss progress is represented by the function W = 235 - 2.5t, where W is her weight in pounds and t is the time in weeks. Oscar's weight loss progress is represented by the table. Who weighed more at the beginning of the show?

• Valerie

• Oscar

Is the relation a function? Why, or why not?

• Yes, because the x-value of 11 has two y-values.

• Yes, because each x-value has only one y-value.

• No, because the x-value of 11 has two y-values.

• No, because each x-value has only one y-value.

• Function
• Not a Function
