Find the height, in feet, of the rock after 10 seconds in the air
A rock is launched from a cannon. Its
height, h(x), can be represented by a
quadratic function in terms of time, x, in
seconds.
After 1 second, the rock is 58 feet in the
air; after 2 seconds, it is 112 feet in the
air.

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
