Function ProjectBryia Lewis :]

My real world problem!

Bryia went to the galleria and got 5 pairs of shoes for 40.25 dollars a piece. How much did she spend in all?

The equation! :)

My equation

y=40.25x or f(x)=40.25xx=the number of shoes I boughty=the total cost

X =??

Independent and Dependent!

My independent is my x which is the number of shoes.

My dependent is my y which is the total cost

Y depends on X The cost depends on how many shoes

Table of values!

x 40.25x y (x,y)

1 40.25(1) 40.25 (1,40.25)

2 40.25(2) 80.50 (2,80.50)

3 40.25(3) 120.75 (3,120.75)

4 40.25(4) 161.00 (4, 161.00)

5 40.25(5) 201.25 (5, 201.25)

Domain and Range!

My domain is {1,2,3,4,5}

My range is[40.25, 80.50, 120.75, 161.00, 201.25]

Continuous and Discrete!

My data is discrete

I can not purchase a just one shoe I have to get a pair.

Is it a function? o_0

My data is a function. Yaay.

My X’s do not repeat

Y-Values

In the end…..

The amount of money she spends all depends on the amount of shoes she buys. So she could have spent 40.25 on a pair but she spent 201.25.
