Question 75196
To find f(-2) just replace x with -2 for every x
{{{f(-2) = -(-2)^3 + 3(-2)^2 - (-2) + 4}}}
{{{f(-2) = -(-8) + 3(4) +2 + 4}}}
{{{f(-2) = 8 + 12 +6}}}
{{{f(-2) = 26}}}


To find f(0) just replace x with 0 for every x
{{{f(0) = -(0)^3 + 3(0)^2 - (0) + 4}}}
{{{f(0) = 0 + 3(0) -0 + 4}}}
{{{f(0) = 0+4}}}
{{{f(0) = 4}}}

To find f(3) just replace x with 3 for every x
{{{f(3) = -(3)^3 + 3(3)^2 - (3) + 4}}}
{{{f(3) = -27 + 3(9) -3 + 4}}}
{{{f(3) = -27 + 27 +1}}}
{{{f(3) = 1}}}
