Because . So what you really have is
which is just
There is no need to actually state in the polynomial since it just equals 1.
Hi people, hoping you can help me understand polynomial functions.
I have been given an example which is the following:
p(x) = 2x^3 + 3x + 1
Coefficient of x^3: 2 - I understand why this is a 2 because it is in front of x^3.
Coefficient of x^2: 0 - I understand this as there is no x to the power of 2.
Coefficient of x^1: 3 - I see why as 3 is in front of the single x.
Coefficient of x^0: 1 - However, I do not see why this is?
