Answer:
F(x) = 1/x^2
Step-by-step explanation:
F(x) = 1/x^2 is
y = 1/x^2
graph goes up to 10 each side
plug in 1,2,3,4,5,6,7,8,9,10 for x and see what y looks like
when x is 1,2,3,4,5,6,7,8,9,10
y is 1,1/4,1/9,etc
This is a triangle with the height 3x and the base 4.
So the area is A= 1/2 * height* base
A= 1/2 * 3x* 4= 6x
The answer is 6x
Hope that userful for you.
