Algebra II

Zeros : (-4, 0) , ( 2, 0)

Minimum : (5, -4)

Maximum : (-1, 3)

Y-Intercept : (0, 2.5)

Increasing : (-5, 3) (All x values)

Decreasing : (3,5) (All x values)

End Behavior (Left) : as x → -∞, y → -∞

End Behavior (Right) : as x →∞ , y → -∞

In everyday life, we constantly use math, whether you know it or not. Amusement Parks and rollercoasters are great example of math, specifically algebra. Rollercoaster designers use polynomial functions in order to create their curves, twists and intervals (increase + decrease). In this example to the left, you see a portion of a rollercoaster, both increasing and decreasing. We can find and graph this portion to find it's polynomial function to determine the numbers used to create this part of the rollercoaster.
