For questions (1)-(5), construct a definite integral or sum of definite integrals which represents the area between the given curves and find the exact value of this integral or sum of integrals. (1). y = 3x + 2, y = 5 - 4x, x =1 and x = 5 (2). y = ex, y = x+8, x =-4 and x = 0 (3). y = 5+2x - x2 and y = 5 - 2x (4). y = 3x2 - 10x - 100 and y = 20 + 15x - 2x2 (5). y = x and y = x ous
