Suppose you are given the function f (x) = a In a + b. What must the parameters a and b equal so that the line tangent to the curve represented by f (a) at (2, 2) has a slope of 2? O A. a = 2 and b = 2 - 2 In 2 O B. a = 2 and b = 2 - 4 In 2 O C. a = 2 and b = 4 - 2 In 2 O D. a = 4 and b = 2 - 2 In 2 O E. a = 4 and b = 2 - 4 In 2
