(a) Sketch the functions f(x) = x + 2x - 7 and g(x) = 2 on the same graph. (b) Determine the coordinates of the points of intersection of the two curves and label their exact values. You are not required to determine coordinates of intersections with zor y axes. (c) Evaluate the finite area enclosed between the two curves. You are expected to show clear working for all parts.
