Determine os valores de x para que ambas as funções, f(x) = -2x+8 e g(x) =3x-6, sejam negativas:​

W-14=t. that i think is the answer idk

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.
