Key Concepts

End Behavior

The end behavior of a polynomial function describes how its values behave as the input grows very large (positively or negatively). This behavior is largely determined by the degree and the leading coefficient of the polynomial. For instance, if the degree is even and the leading coefficient is positive, both ends of the graph will rise, whereas different combinations yield different behaviors.

Factored Form and Zeros

Expressing a polynomial in its factored form simplifies the process of finding its zeros, as each factor corresponds to an x-intercept. This form also aids in understanding the multiplicity of the zeros, which influences the graph's shape near the intercepts; for example, a zero with an odd multiplicity will cross the x-axis, while one with an even multiplicity will touch and turn away.

Polynomial Functions

Polynomial functions are algebraic expressions composed of variables raised to non-negative integer powers and coefficients. They form continuous and smooth graphs that are defined for all real numbers, making them easy to analyze for intersections, turning points, and end behavior.

Intercepts

Intercepts are the points where the graph of a polynomial crosses the coordinate axes. The x-intercepts (or zeros) of the function are found by setting the function equal to zero and solving for x, while the y-intercept is determined by evaluating the function at x = 0. Identifying these intercepts is key in sketching an accurate graph.
