I need help on these 3 calculus problems:

Let -atb, if a -2(and x * b) (a) For what value(s) of b is f continuous at -2? Answer: b = (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 = (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 setUse the given graph of the function f to determine the type of discontinuity at each sc-value. J choose one removable Jump infinite 2. What type of discontinuity does f have at a: = 2? 3. What type of discontinuity does f have at a: = 2? ' choose one 9 4. What type of discontinuity does f have at :c = 4? Note: You can click on the graph to enlarge the image. According to the Intermediate Value Theorem, which of the following intervals must contain a zero of the function f (w) = m3 + 3x + 7 7 A [-2,-1] 6 [-1,0] 6 [0,1] 6 [1,2] A None of the above
