Find the limits in a through c below for the function fx x2

Find the limits in a [through c] below for the function f(x) = x^2 - x - 2/x - 2 a. Select the correct choice below and fill in any answer boxes in your choice a. lim_x rightarrow 2^- f(x) = B. The limit does not exist.

Solution

f(x)=(x²-x-2)/(x-2)=(x-2)(x+1)/(x-2) = x+1

lim f(x) for x tends to 2^-= -2+1=-1

Therefore limit x tends to 2^- of f(x)=-1
