Alex17521 [72]
F(-2).....this is basically saying that when x = -2, what is y

so f(-2) = 2

because f(x) is the same as y...but when u have f(-2)....this is saying x = -2 and they are wanting to know what y is....and when x = -2, y = 2....so f(-2) = 2

If an object is dropped from a height of 144 feet, the function h(t)=-16t^2+144 gives the height of the object after t seconds.
shtirl [24]

Answer:

A. 3s

Step-by-step explanation:

The height of the object after t seconds is given by:

h(t) = -16t^2 + 144

When will the object hit the ground?

It hits the ground after t seconds, and t is found when h(t) = 0. So

h(t) = -16t^2 + 144

0 = -16t^2 + 144

16t^2 = 144

t^2 = \frac{144}{16}

t^2 = 9

t = \sqrt{9}

t = 3

3 seconds, so the correct answer is given by option a.
