  • f(x)=-3x^3+x^2-3


\\ \sf \longmapsto f(2)


\\ \sf \longmapsto -3(2)^3+(2)^2-3


\\ \sf \longmapsto -3(8)+4-3


\\ \sf \longmapsto -24+1


\\ \sf \longmapsto -23

Answer:

D

Explanation:

f(x) = -3x^3 + x^2 – 3 f(2) means that wherever you see a x, put in a 2.

f(2)= -3(2)^3 + (2)^2 - 3

f(2) = -3*8 + 4 - 3

f(2) = - 24 + 1

f(2) = - 23
