I need help with all question please

In the problems that follow (9 and 10) , you will investigate integration and finding the integral using 10) f(x) =x3+2x2- 3x, g(x)=0 ometric concepts. The area that is given by the shaded region shows how positive areas are above the x -axis areas that contribute negative results are below the axis. Geometrically: A(total) = A(above) - A(below) : assuming all areas are positive But when we integrate, we don't subtract because integration does that implicitly. splitting up the integral gives the correct area a) in each problem, find the area using integration b) Then find the integral using areas; draw the figure, split the integral and find the individual areas and sum. 9) Graph first the function y = =2x + 6, then integrate, following directions (a) and (b) 1 ( - 2 x + 6 ) dx
