d at the girls. “The ball hung in the air for at least 10 seconds”, he exclaimed. The formula for this hit is: h(x)=-16x2+83x+4 where h is the height of the ball and x is the number of seconds the ball is in the air. A.

Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
As Juan continued his hitting practice
showing off his abilities, one of the balls
flew over the center field stands and into
the parking lot. “Did you see that shot”, he
yelled at the girls. “The ball hung in the air
for at least 10 seconds”, he exclaimed.
The formula for this hit is:
h(x)=-16x2+83x+4 where h is the
height of the ball and x is the number of
seconds the ball is in the air.
A. How can Juan provide proof that the
the ball actually hung in the air for 10
seconds?
B. How long did the ball hang actually
hang in the air?
