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
