Question 1036832

A cubic polynomial function f(x) has leading coefficient -2 and intercepts the y - axis at 2. If f(1) = 1, and f(-2)= -2, find f(-1) and write the complete function.
<pre>Complete function: {{{highlight_green(f(x) = - 2x^3 - 3x^2 + 4x + 2)}}}
{{{f(- 1) = - 2(- 1)^3 - 3(- 1)^2 + 4(- 1) + 2}}}
{{{f(- 1) = - 2(- 1) - 3(1) - 4 + 2}}}
{{{f(- 1) = 2 - 3 - 4 + 2}}} =========> {{{highlight_green(f(- 1) = - 3)}}}
