Value of a Polynomials
If p(x) is a polynomial in x, and if k is any real number, then the value obtained by replacing x by k in p(x), is called the value of p(x) at x = k, and is denoted by p(k).
Example: What is the value of p(x) = 2x2 − 3x + 1 at x = 2?
Substitute 2 for x in p(x)
p(2) = 2(2)2 − 3(2) + 1
= 8 − 6 + 1
= 3
Therefore, the value of p(x) at x = 2 is 3.
