Explain why f(x) = x^2+4x+3/x^2-x-2 is not continuous at x = -1. a. f is not defined at x = 0 c. f is not defined at x = -1 b. f is not defined at x = 1 d. f is not defined at x

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.

Hold on lemme do the work
