10. on a windy morning, a hot air balloon starts rising
and flying away from the top of a hill. the
altitude, h, in feet, of the balloon x hours after
starting its ascent from the hill, can be modeled by
the function

h(x) = -16x² + 64x + 80.

part a: what is the y-intercept for this function?
what does the y-intercept represent in the given
situation? use your equation to explain how you
found your answer.

part b: there is a positive and negative x
intercept for this function. what is the positive
x-intercept? explain what this x-intercept
represents in the given situation. show your work.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,
