An object is thrown upward from the ground with an initial velocity of 48 feet per second. The height h(t) in feet of the object after t seconds is given by the polynomial function h(t)=-16t2+48t . (a) Write an equivalent factored expression for the function h(t) by factoring -16t2+48t.

(b) Find h(4) by using h(t)=-16t2+48t and then by using the factored form of h(t).

(c) Why are the values found in part (b) the same?

this doesn't make sense lol

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

won't that be plagrisim thought?
