Understanding Polynomials
A polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.
Degrees of a Polynomial
The highest exponent in the polynomial determines its degree:
- Linear: Degree 1 (e.g., 2x + 3)
- Quadratic: Degree 2 (e.g., x² - 4x + 4)
- Cubic: Degree 3 (e.g., 3x³ + x)
This evaluator replaces the `x` variable with the number you provide, returning the specific plot point (y-value) on the graph of the polynomial function.
