Question

A pitcher throws a baseball.
The path of the ball is modeled by the equation p(x) = - 0.013x2 + 0.02x + 7.4.
How high was the ball when it left the pitcher's hand?

Answer 1

Answer:

If the units in the equation are in feet, it lef5t at a height of 7.4 feet (or meters, etc.).

Step-by-step explanation:

p(x) = - 0.013x2 + 0.02x + 7.4

When x, the time, = 0 [just before it leaves the pitcher's hand]

p(0) = 7.4
