Interpreting Functions

slide2

Question 1

WardyTee’s prints t-shirts for $11 each. There is also a startup cost of $50 for the order. Write an equation that models this situation.

slide3

Question 2

Sketch a linear graph that is decreasing.

slide4

Question 3

Rob is throwing a birthday party at All-Play. It will cost him $100 to reserve the space at All-Play. In addition, he has to pay $15 for each of his guests to receive tokens. Write an equation that represents the total cost (y) of the party.

slide5

Question 4

Sketch a linear graph that has a zero slope.

slide6

Question 5

  • Harry is moving to a new home and needs to rent a truck. He has to pay $19.95 for the truck. He then has to pay $0.70 for every mile that he drives the truck. Write an equation that represents the total cost (y) of renting the truck.
slide7

Question 6

  • Sketch a graph with a constant rate of change and with an initial value of 3.
slide8

Question 7

  • Sally is raising money by selling t-shirts for her choir group. She had to pay $40 for the box of t-shirts. The equation y=8x – 40 represents this situation where x is the number of t-shirts sold and y is the total amount of money raised.
  • In at least one sentence, describe what the 8 represents in the context of this problem.
slide9

Question 7 cont.

  • Sally is raising money by selling t-shirts for her choir group. She had to pay $40 for the box of t-shirts. The equation y=8x – 40 represents this situation where x is the number of t-shirts sold and y is the total amount of money raised.
  • In at least one sentence, explain why the equation is subtracting 40.

Question 8

  • The graph to the right shows Mary’s trip to the store.
    • Between which interval(s) was her speed increasing?
slide11

Question 8 cont.

  • The graph to the right shows Mary’s trip to the store.
    • Between which interval(s) did her speed stay the same?
slide12

Question 9

  • George and Tommy are running home. George gives Tommy a head start of 4 minutes. George runs at a pace of 7 minutes per mile and Tommy runs at a pace of 8 minutes per mile. The equations that represent George and Tommy’s runs are below.
  • George: y = 7x
  • Tommy: y = 8x + 4
  • Describe in at least one sentence what the variable x represents in the equations above.
slide13

Question 9 cont.

  • George and Tommy are running home. George gives Tommy a head start of 4 minutes. George runs at a pace of 7 minutes per mile and Tommy runs at a pace of 8 minutes per mile. The equations that represent George and Tommy’s runs are below.
  • George: y = 7x
  • Tommy: y = 8x + 4
  • Describe in at least one sentence what the variable y represents in the equations above.
slide14

Question 10

  • Create a story that has a rate of change of 8 and an initial value of 10. Define the variables and write the equation that represents the story.
