Answer:
Step-by-step explanation:
We are given that a graph of a polynomial function.
We have to find the factored form of the given graph polynomial function by assuming that it has no constant factor.
To find the factored form of polynomial function we will find the x-intercept of polynomial function.
x- Intercept: It is defined as the value of x for which the value of f(x) equals to 0.
We can see that form given graph,
The value of f(x) is zero at x= 2 and x=-2.
Now, multiply (x+2) and (x-2) then, we get factored form of polynomial of given graph
Hence, the factored form of the polynomial function of given graph is given by

y=-0.04x^2+8.3x+4.3
when the rocket reaches the ground (when height=0, ie when y=0), then the rocket will land, find the x coordinate
set y=0
0=-0.04x^2+8.3x+4.3
use quadratic formula
if you have ax^2+bx+c=0, then
x=
a=-0.04
b=8.3
c=4.3
x=
x=208.017 or -0.516785
xrepresents horizontal distance
you cannot have a negative horizontal distance unless you fired and theh wind blew it backwards
therefor x=280.017 is the answer
