Expert Solution
Step 1

Consider the given function,

|x 2x1x< -1 f(x)= 1; x2-1
Step 2

Find the limit value as per the given question,

(1). lim f(xlim(x +2x+1) x1 =(-1)+2(-)+ 1-2+1 =0 So, lim f(x)0 x (b). lim f(x) lim x1 -1+1 -1 = ve-1 =0 thus, lim f(x)0 (e). lim f(x)lime -1+1 1 =0 So, lim f(x) 0 x1
