1 ) Find the area of the region bounded by the graph of f(x) = (x - 4)# and the x-axis between x=2 and x=6. 5 points If you use substitution, also substitute the limits! 2) Evaluate the following definite integrals (exact solutions!). State the method you are using (basic integrals, substitution, integration by parts, tabular integration). If you use substitution, also substitute the limits! a) 2x + 1 6 points dx ( x - + x + 1 )2 30 0
