find the total area of the region between the curve and the x- axis
1) y=2-x, 0≤x≤3
4)y= x^3-4x, -2≤x≤2
The Attempt at a Solution
I've tried using my graphic calculator to see what the graphs looked like then i copied some of the points off of the table of x and y values so i could hand draw what i saw on the calculator. i'm completely stumped because i don't know if finding the total area for question 1 will be the same for the rest of the problems because it is a straight line not a curve. i am also getting net area confused with total area and don't know the difference between the 2. what about using the Riemann sums or trapezoidal rule? would i have to use it in order to solve these problems?
