FINAL PROJECT

PART 1

THE QUADRATIC

• Using the points (2,8)(12,26)(-12,-5)
• I found a quadratic equation to model this senario
• It is Y=.036X^2+1.29X+5.27

THE EXPONENTIAL

• To find an exponential equation two points are nesesary
• I used (2,8) and (12,24)
• The exponential function that goes through these to points is
• Y=6.3*1.12^X

LINEAR EQUASION

• Like an exponential equation a linear requires just 2 points
• For the points of (2,8) and (12,26) the linear equation is
• Y=1.8x+4.4

RATIONAL EQUASION

• When a variable is put in the denominator of a fraction
• it becomes a rational equasion. A rational equation that goes
• through points, (2,8) and (12,26) is, Y=(-43.19/X)+29.6

A PROBLEM

• In February there are 8 hippos on an island, by December
• there are 26 hippos on the island. There is an unlimited food supply
• and no predators on the island.
• The exponential function will model this best as each hippo will help
• the population grow further, just as exponential equations grow at ever Increasing rates.

THE PROBLEM (CONTINUED)

• For example if X=20 it would represent
• August of the next year. At that time there would be
• 60 hippos on the island, and one that is is 7/10 through
• her pregnancy.

B

• When a function is multiplied out in
• Standard form it becomes much harder to shift
• as there are multiple x and there is no easy way to
• Directly change one aspect of the x.
