Question 153855
I think what they are askig you to do is evaluate the given function at the value where x=-4.1

Given P(x) = –x^3 + 4x^2 – 2.1 evaluate at x = -4.1
P(-4.1) = –(-4.1)^3 + 4*(-4.1)^2 – 2.1
P(-4.1) = –(-68.921) + 4*(16.81) – 2.1
{{{P(-4.1) = 68.921 +  67.24 – 2.1}}}
{{{P(-4.1) = 134.061}}}

To the nearest tenth is {{{134.1}}}
