I need solve question 3 and 4

TASK 2: ANTIDIFFERENTIATION The graph of y = x3 - 7x2 + 14x - 8 is given in Figure 1. (1) Find the following integral I = (23 - 7x2 + 14x - 8) dac 2 (2) Find the following integral I = (23 - 7x2 + 14x - 8)dx (3) Use the solutions to Q1(a-b) to find the area bounded by the curve y = 23 - 7x2 + 14x - 8 and the x-axis between x = 0 and x = 2.2 TRIMESTER 1, 2022 (4) Find the integral I = (23 - 7x2 + 14x - 8)do. Explain why this is not the same as the area you found in Q1(c). y L -2 -1 1 2 FIGURE 1. Graph y = 23 - 7x2 + 14x - 8
