Exam version: 779. Let a be a constant and let f(x) be a function with domain (-,). Assume that f satisfieslimx2-f(x)-f(2)x-2=4a, and ,limx2f(x)-f(2)x-2=9.Which of the following statements is TRUE?(a)f'(2)=a49.4a=a(b) If a=5, then f'(x)=9 for all values of x.a=5(c)f'(2) does not exist for all values of a.(d) If a5, then f is not continuous at x=2.(e) If a=5, then f'(2)=9.Consider the functionExplain why the wrong answers ate incorrect
