I am having some trouble with these questions. I am not sure how to find the areas

In each of the following problems, plot the functions and use the plot to find the area. 1. Find the area of the region bounded by f (x) = 2 x - x and g(x) = x. 2. Find the area of the region bounded by f (x) = x' - 3x - 2x + 4 and the line x + y = 1. To plot the line correctly, solve for y and call it g(x). So g(x) = 1 - X
