Answer:

Step-by-step explanation:

f(x)=9x³-3x²+x-5

g(x)=x-2/3

f(2/3)=9*(2/3)³-3*(2/3)²+2/3-5

        =9*8/27-3*4/9+(2-15)/3

        =8/3-4/3-13/3

        =(8-4-13)/3

        =-9/3

        =-3

Answer:

-3

Step-by-step explanation:

g(x) = x - 2/3

   x = 2/3

f(2/3) = 9*(2/3)³-3*(2/3)²+2/3-5

        = 9*8/27-3*4/9+(2-15)/3

        = 8/3-4/3-13/3

        = (8-4-13)/3

        = -9/3

        = -3
