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
thanks

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
