Question 53278
All you have to do is to substitute the given values of the function, for x in the equation.
{{{f(x) = -x^3 - 3x^2 + 3x + 7}}} Find f(-1) by substituting -1 for x.
{{{f(-1) = -(-1)^3 - 3(-1)^2 + 3(-1) + 7}}}
{{{f(-1) = 1 - 3 -3 +7}}}
{{{f(-1) = 1 -6 + 7}}}
{{{f(-1) = 2}}}

{{{f(0) = -(0)^3 - 3(0)^2 + 3(0) + 7}}}
{{{f(0) = - 0 - 0 + 0 + 7}}}
{{{f(0) = 7}}}

{{{f(2) = -(2)^3 - 3(2)^2 + 3(2) + 7}}}
{{{f(2) = -8 -12 + 6 + 7}}}
{{{f(2) = -20 +13}}}
{{{f(2) = -7}}}
