3 0.5 points 4 0.5 points In evaluating f x (1 + 23) ' dx. Evaluate / (7x - 4) dx we make the substitution u =_ O -1.5 O 1+ 23 O 6 0.5 points O -2 The limit of the Riemann sum is the definite integral of fover [a, b]. if the limit exists. O O -0.5 True O O (1+ 23) -2.5 False 5 1 point Find the area bounded by the curve y = z' + x + 4 , the x - aris , from = =1 to = = 3 . 8 1 point Consider the graph below. Which of the following is the correct setup for the area of the shaded region. (1,1) (0.0) O O A= [(x2) - (2x - 27) ] dx 4 sq. units O A= [(2x - z?) - (x7) ] dx O 32/3 sq. units O A= [(x]) - (2x - 27) ] dy O 62/3 sq. units O O A = So [(2x - 23) - (22)] dy 4/3 sq. units
