lifewmylilweeb · Answer

and the equation i graphed was
 -32x^2+64x+40

mhanifa · Answer

The maximum in terms of the quadratic function is the vertex. And you have the value of f(x).

lifewmylilweeb · Answer

so what does the maximum represent

mhanifa · Answer

What do you think it represents?

lifewmylilweeb · Answer

we cant put the definition of what a maximum is we have to out what the maximum represents on the graph

lifewmylilweeb · Answer

and i honestly dont know what the maximum represents

lifewmylilweeb · Answer

is it the number of feet it fell per second

mhanifa · Answer

Remember the beginning of the question. What is this about?

mhanifa · Answer

In terms of this question, one of the x-intercepts doesn't make sense. Do you know why?

lifewmylilweeb · Answer

because it is a negative?

mhanifa · Answer

I suggest you look at the graph and imagine it is the trajectory of the ball. Yes, it is the time but what do you understand from the graph?

lifewmylilweeb · Answer

huh?

mhanifa · Answer

Can the time be negative?

mhanifa · Answer

The ball is in travel starting from 0 seconds until it hits the ground at 2.5 sec mark

lifewmylilweeb · Answer

i know that

mhanifa · Answer

So what's you final answer? Only one of x-intercepts but not both

lifewmylilweeb · Answer

huh?

mhanifa · Answer

"The x-intercept (2.5, 0) represents the amount of time it will take the ball to hit the ground"
