Question

PLEASE HELP ME PLEASEEEEEEEEEEEEEEEEEEE!

Jacob is practicing javelin throws. He throws the javelin from a height of 6 feet. The height of the javelin, h(x), in relation to the horizontal distance that it covers, x, can be modeled by a quadratic function.

Each of the following functions is a different form of the quadratic model for this situation. Which form is most helpful in determining the horizontal distance the javelin covers?

Answer 1

The most helpful representation would be option C.

Explanation:

The horizontal distance traveled corresponds to one of the roots of the quadratic equation.

h(x) = -0.01(x-150)(x+4)

In this case, option c presents the roots of the polynomial, which answers are

x = -4

x = 150

Since we are talking about positive distances, the first option gets discarded.

So the horizontal distance is x = 150 feet
