Answer:
The polynomial function from number 2 is:
f(x) = 4x^3 - 5x^2 + 2x - 1
To write this in standard form, we need to arrange the terms in descending order of degree:
f(x) = 4x^3 - 5x^2 + 2x - 1
f(x) = 4x^3 + (-5x^2 + 2x - 1)
f(x) = 4x^3 - 5x^2 + 2x - 1
So the standard form of the polynomial function is:
f(x) = 4x^3 - 5x^2 + 2x - 1
