Question

The height of a ball in meters is modeled by fx 5x 2 50x, where x is the time in seconds after it is hit. How long is the ball in the air

Answer 1

Equation is incorrect

Explanation:

The equation is not written correctly. It is written with no arithmetic signs linking the expressions. One might assume it is f(x) = 5x^2 + 50x, but even so, something is still wrong.

The equation tells us that the ball will never return to the ground after it is hit. There are no nonzero positive values of time, x in seconds) for which this equation will produce the "0" for the height at ground level.

Please check the equation.
