My Real World Problem • Amber and her 4 friends want to buy a Soda. A soda cost 1.00 for each person. How much does sodas cost for each person? Friends
The Equation • The Equation to my problem is Y=1.00X or f(x)=1.00x The Y is the cost of soda all together. The X is the number of people.
Independent and Dependent • The Independent Variablesis how many people buying sodas. • The Dependent Variables is the cost of the sodas. We know that yDEPENDS on x
Table X Y=1.00x Y X,Y 1 1.00(1) 1.00 1, 1.00 2 1.00(2) 2.00 2, 2.00 3 1.00(3) 3.00 3, 3.00 4 1.00(4) 4.00 4, 4.00 5 1.00(5) 5.00 5, 5.00
Domain and Range Domain- the x values Range- the y values Domain:(1,2,3,4,5) Range:(1.00,2.00,3.00,4.00,5.00) Range Domain
Is It Continuous or Discrete? • No it not continuous, it is discrete because you can’t buy ½ soda so it is discrete.
Is it a Function? • Yeah because my X don’t repeat. • One x values is match to a y values. • A function is where the x don’t repeat.
What would happened? • It cost 1.00 per person and all together it was 5.00 for 5 friends. When my sister and her friends came back home they were going to stay, but my sister friends leave. When my sister open her soda it went all over her and it got her clothes wet. It turn out that one of my sister friends shake up her soda to play with her they said they are sorry and have never do it again.
