If h(x) =4x-8 and j(x) =-x solve h[j(3)]

J(x) = -x
h(x) = 4x - 8
h(j(x)) = 4(-x) - 8

h[j(3)] = 4(-3) - 8
h[j(3)] = -12 - 8
h[j(3)] = -20

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.
