FUNCTION PROJECTAlysha Green

Real World Problem

Mariah and Natasha are going skating with three other friends. If tickets cost $5.00 a piece, then how much will it cost for all of them to go.

The Equation

y= 5.00x or f(x)= 5.00x

x= The number of skating ticketsy= The total cost

Independent and Dependent

The independent variable is x, the number of skating tickets.

The dependent variable is y, the total cost.Since y depends on x, the total cost

depends on the number of skating tickets.

Table of Values

x 5.00x y (x,y)

1 5.00(1) 5.00 (1,5.00)

2 5.00(2) 10.00 (2,10.00)

3 5.00(3) 15.00 (3,15.00)

4 5.00(4) 20.00 (4,20.00)

5 5.00(5) 25.00 (5,25.00)

Domain and Range

The domain is D:{1,2,3,4,5}The range is R:

{5.00,10.00,15.00,20.00,25.00}

Is it Continuous or Discrete?

It is discrete, because it only contains points.

Is this a Function?

Yes, because my x values do not repeat.

Do NOT repeat
