Please submit using your Crowdmark link for this assignment by the due date. (1) Find the following limits, if they exist, or indicate that they do not exist. If the limit does not exist, but the function values tend towards or -, indicate that also. (a) lim, 1 (b) lim-4-2 5x+2 (c) lim 1x+00 x+x+7 2+2r+158 (d) lim-- (+1/x) x + x +1 (2) Find the values of a that make the function f(x) continuous for all x ER and justify your answer. f(x)= x + 5x+7 x + a if x -2 if x < -2.
