Multiple Choice

A baseball is thrown up into the air and the height of the baseball, in feet, x seconds after being thrown, can be modeled by the equation:

$$f\left(x\right)=-16\left(x-3\right)\left(x+5\right)$$

Where woud the x-intercepts of the graph be?

• (-3, 0) , (5, 0) and (-16, 0)

• (3, 0) , (-5, 0) and (16, 0)

• (-3, 0) and (5, 0)

• (3, 0) and (-5, 0)

A baseball is thrown up into the air and the height of the baseball, in feet, x seconds after being thrown, can be modeled by the equation:

$$f\left(x\right)=-16\left(x-3\right)\left(x+5\right)$$

If the x-intercepts are (3,0) and (-5,0), what would that tell us about the baseball?
