im completely stumped on this problem. ive been looking at it for an hour with no progress at all. i have the solutions manual for this problem, as this is a college class but, i dunt understand it at all. some help would be greatly appreciated. and maybe i could help someone with a different topic.

problem:
use the limit process to find the area of the region between the graph of the function and the x-axis over the indicated interval.

Function: Y= -2x+3 interval: [0,1]

some help would be awesome because im getting so stressed trying to figure out this problem.

y= -2x +3
intergrate this function gives

-x^2 + 3x +c

apply the limit range

Area = (-(1)^2 +3x 1) - (-(0)^2 +3x 0)
= 2 - 0
=2

Hope the -(1)^2 is correct.....

Not quites sure what you mean by using the definition as you are just stating the theory behind the idea of what an intergration is. Do you understand intergration methods?
