An apple is launched directly upward at 64 feet per second from a platform 80 feet high. The equation for this apple’s height h at time t seconds after launch is h = -16^2 + 64t + 80. What platform height was the Apple launch from?

How long was the Apple in the air?

When did the Apple reach its maximum height?

What was the Apple’s maximum height?

What is the domain for the function in this context?

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

i can't solve unless i know what the line is
