When it says graph the image, it's asking me to graph a reflection across x = -2. what's the answer look like?

The reflection across x = -2 will be x = 2.

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.
