I need help on these 2 questions:

Question 1 part A and D

Question 2 part B and D

x2+ 3, 2- 5 + lim f(x) = 40 lim f(x) = 1.5 x +6- x-+6+Let - x + b, if a -2(and x * b) (a) For what value(s) of b is f continuous at -2? Answer: b = 1 (b) For what value(s) of b does f have a removable discontinuity at -2? Answer: b = (c) For what value(s) of b does f have an infinite discontinuity at -2? Answer: b = -2 (d) For what value(s) of b does f have a jump discontinuity at -2? Write your answer in interval notation. Answer: b is in the set
