Problem:• Kim went to the pumpkin patch. The price for pumpkins were .25 cents per pound. If I picked out a pumpkin that was $20. How many pounds was Kim’s pumpkin?

EquationY=.25

orF(x)=.25 x

x

Independent and Dependent Variables

• Independent- number of pounds

•Dependent- cost

Is this a function??

•Yes it’s a function because the x

values don’t repeat.

Domain and Range

•Domain- The x values (0,1,2,3,4)

•Range- The y values (0,.25,.50,.75,1)

Continuous or Discrete?

• It’s continuous because it’s a

straight line and all the points connect.

Table:X Y=.25(X) Y (X,Y)

0 .25*0 0 (0,0)

1 .25*1 .25 (1,.25)

2 .25*2 .50 (2,.50)

3 .25*3 .75 (3,.75)

4 .25*4 1 (4,1)
