Question 153855: Find the indicated value of the polynomial. Match your result to the correct answer below. Round to the nearest tenth.
P(x) = –x3 + 4x2 – 2.1, P(–4.1)
If you could explain this to me I would appreciate it

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%28-4.1%29+=+68.921+%2B++67.24+%96+2.1
P%28-4.1%29+=+134.061
To the nearest tenth is 134.1

P(x) = –x^3 + 4x^2 – 2.1, P(–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) = 134.06
