Question

The expression - 16x + 24x + 4.2 represents the height of a ball, in feet, × seconds after it is thrown. What does 4.2 represent in this context?

Answer 1

4.2 represents the initial height of the ball.

Explanation:

h(x) = -16x² + 24x + 4.2

At x = 0, h(0) = 4.2

4.2 represents the initial height of the ball.
