How do you graph fractions/mixed numbers on a coordinate plane?

The easiest way to graph fractions/mixed numbers onto a coordinate plane is to first take those fractions/mixed numbers and put them in decimal form. That can either be done by hand or by a calculator. Take 4 for instance. Converting that to decimal form would be 4.875.

When the ball hit the ground, the height of the ball will be zero. So using the value of h(x) as zero in the given equation, we can find the time in which the ball will hit the ground.

0 = -(x-2)^2 + 16

(x-2)^2 = 16

x-2 = 16

x-2 = 4

x = 6

This means the ball will hit the ground 6 seconds after Amir threw it.
