2. Sketch the curve y = 3x + 1 between x = -2 and x = 4. Determine by integration the area enclosed by the curve, the x- axis and ordinates x = -1 and x = 3. Use a numerical integration method to find the area and compare your result with that obtained by integration. 2. Sketch the curve y = 3x + 1 between x = -2 and x = 4.
