Two functions are defined as shown. f(x) = -1/2x – 2 g(x) = –1 which graph shows the input value for which f(x) = g(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.
