Alissia’s Function Slide Show!!
Real- World Problem
• Faith and 3 of her friends wants to go to the movies, if the tickets cost $7.50 each plus popcorn which cost 3.50 each not including tax, how much will cost for them to go?
Equation
• The equation to my problem is… y= 11.00x or
J(x)=11.00x
y=The total cost of the tickets and popcorn
X= The number of people
X= independent , y=dependent
• The independent variable is x which is the number of people.
• The dependent variable is y which is the total cost of the tickets and popcorn.
We know y depends on x So the total cost depends on the number of people.
Is This a Function? & Why?
• yes, because the x’s do not repeat.
Domain & Range!
• The domain of a relationship is the set of permissible x values. Domains can be continuous or discrete.
• The range of the relationship is the set of permissible y values.
My domains are [1,2,3,4] & My ranges are [11.00, 22.00, 33.00, 44.00]
Continuous Or Discrete
• Discrete. Why? Because there are number
between 11.00- 44.00!
Function Notation
• Equation: y= 11x• Function Notation: F(x)= 11x
