The numerical value of a polynomial is the result of evaluating the polynomial for a specific value of the variable.
What is the numerical value of a polynomial?
To find the numerical value of a polynomial, you simply substitute the value of the variable into the polynomial expression and simplify the resulting expression.
For example, to find the numerical value of the polynomial:
2x + 1 when x = 4, you would substitute 4 for x in the expression and simplify as follows:
2x + 1 = 2(4) + 1
= 8 + 1
= 9
The numerical value of the polynomial 2x + 1 when x = 4 is 9
