Suppose the region on the left in the figure (with blue shading) has area is 27, and the region on the right (with green shading) has area 9. Using the graph of $f(x)$ in the figure, find the following integrals. $\displaystyle \int_a^b f(x) \, dx =$ $\displaystyle \int_b^c f(x) \, dx =$ $\displaystyle \int_a^c f(x) \, dx =$ $\displaystyle \int_a^c |f(x)| dx =$
