Answer:
The area between the curves is 4 square units.
Explanation:
We want to find the area bounded by:
y = x
x = 0
in the interval x = 1, x = 3
This is simply equal to the integral of the function f(x) = x between x = 1 and x = 3
Written as:
And the integral of x is equal to x^2/2
Then:
The area between the curves is 4 square units.
