$${f}\left(\mathrm{2}\right)−{f}\left(\mathrm{0}\right)=\int_{\mathrm{0}} ^{\mathrm{2}} {f}'\left({x}\right){dx}=\boldsymbol{{A}}_{\mathrm{1}} \approx\frac{\mathrm{2}}{\mathrm{3}}×\mathrm{2}×\mathrm{3}=\mathrm{4} \\ $$$${f}\left(\mathrm{4}\right)−{f}\left(\mathrm{2}\right)=\int_{\mathrm{2}} ^{\mathrm{4}} {f}'\left({x}\right){dx}=\boldsymbol{{A}}_{\mathrm{2}} \approx−\frac{\mathrm{2}}{\mathrm{3}}×\mathrm{2}×\mathrm{1}=−\frac{\mathrm{4}}{\mathrm{3}} \\ $$
