Options
- A4
- B14 3
- C7
- D26 3
Correct answer
D. 26 3
Step-by-step solution
f(x) = x + 1 x - 1 dx f(x) = x - 1 + 2 x - 1 dx f(x) = ( x - 1 + 2 x - 1 ) dx f(x) = 2 3 (x - 1)^ 3/2 + 4(x - 1)^ 1/2 + C f(5) = 2 3 (4)^ 3/2 + 4(4)^ 1/2 + C = 16 3 + 8 + C = 40 3 + C f(2) = 2 3 (1)^ 3/2 + 4(1)^ 1/2 + C = 2 3 + 4 + C = 14 3 + C f(5) - f(2) = 40 3 - 14 3 = 26 3 Answer: 26 3
