The path of a baseball after it has been hit is modeled by the function h = -0.00320 + d + 3, where h is the height in feet of the baseball and d is the distance in feet the baseball is
from home plate. What is the maximum height reached by the baseball? How far is the
baseball from home plate when it reaches its maximum height?

its is 3000 feet

Step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
