<h3>Quadratic functions</h3>

Quadratic functions are functions that has a leading degree of 2.

Given the equation that represents  roller coaster’s height as shown

h = –0.025t^2 + 4t + 50

The coaster will reach the ground when h = 0

Substitute

0 = –0.025t^2 + 4t + 50

Factorize

On factorizing, the time it took the rider to reach the ground level is 171.651seconds
