If f(x) = \x1 + 9 and g(x) = -6, which describes the value of (f + g)(x)? (f + g)(x) > 3 for all values of x (f+g)(x) < 3 for all values of x (f+ g)(x) < 6 for all values of x (f+g)(x) > 6 for all values of x plz

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.
