Evaluating the integral by interpreting it in form of area.

For question a), I know from the book that the area can be found by taking the area of the trapezoid yielding 4. But if 0 and 2 are
the domain of the integral wouldn't it just be the area of the triangle? I am sorry for my articulation, English is not my native
language.

Re: Evaluating the integral by interpreting it in form of ar

I also have one more quick question if you are in will to engage towards.

What do I do when the question requests that I evaluate an integral by interpreting it in terms of area?

Such as:

let S= integral symbol (tell me how to add the integral symbol)
let IxI be absolute value of x.

S(1-x)dx
and
S(IxI)dx

Re: Evaluating the integral by interpreting it in form of ar

The integral of a function from a limit of to is equal to the area enclosed by the curve between the x-axis under those points.
For the image question


Similarly, you can find other areas.
