Good afternoon sir/mam, i need help for this example problem we have in class and to understand the next chapter thank you

5 .By finding an antiderivative , calculate each integral .(5 pts each )a .So 3 x 2 dixb .fox ' dx ( Hint : What would it be if you were asked for ( 8 x 7 dix ? )C .So* sinx dix6 .Calculate |_ |* + 21 dix using each of the following methods , and reconcile youranswers :"(10 pts each )a .Sketch the graph of Y = 1* + 21 and sum up two triangular areas .b .Write | x + 21 = [ * + 2 if* 2 - 211 - x - 2 if * < - 25; and use antiderivatives as appropriateto find the integral . You'll need two antiderivatives and two integrals to do thisproblem .
