I'll fan, medal, whatever you like, just pls
the graph below shows the height of a kicked soccer ball f(x), in feet, depending on the distance from the kicker x, in feet:

graph of quadratic function f of x having x intercepts at ordered pairs 0, 0 and 0, 20. the vertex is at 10, 15.

part b: what is an approximate average rate of change of the graph from x = 12 to x = 15, and what does this rate represent? (4 points)

1.4

2.3

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

what are the statements? and what do you mean by "216 2 1 6"?
