What is (f - g)(x)?
f(x) = 3x
g(x) = 3x2 – 3x

-3x^2 +6x

Step-by-step explanation:

f(x) = 3x

g(x) = 3x^2 – 3x

(f - g)(x) = f(x) - g(x)

            = 3x - (3x^2 -3x)

 Distribute the negative sign

             = 3x - 3x^2 +3x

Combine like terms

              = -3x^2 +3x   +3x

             =-3x^2 +6x

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.
