Homework Due-

• Homework 9: Bigger Means Smaller

Homework Assigned-

• Homework 10: Difficult Denominators
• Homework 11: An Average Drive
• POW 7: One Mile at a Time

Class Agenda

1. Go Over Homework 9: Bigger Means Smaller

• Family of Reciprocal Functions

2. Don't Divide That!

• Why doesn't dividing by zero make any sense?
• Look at the traits of the graphs, reciprocal functions

3. "Return of the Shadow"

*Hints

• Draw a diagram of the situation
• Use cross multiplication to find the missing component, the length of the shadow.

Family of Reciprocal Functions Notes

K=constant

Y = K/X

• y is inversely proportional to x, inverse variation

Y = KX

• y is directly proportional to x, direct variation
