Study Notes

Polynomial Functions

Even/Odd Functions: Determine if a function is even or odd by analyzing its graph or equation
Leading Coefficient: The leading coefficient determines whether the graph goes up or down as x approaches positive or negative infinity
Degree: The degree of a polynomial function (the highest power of x) determines the end behavior and number of turning points
Zeros (and Multiplicity): Zeros are the x-values where the function crosses the x-axis. The multiplicity of each zero tells how many times that zero is repeated
Factored Form: A factored form of a polynomial equation can be used to find its zeros, which are the values where the function equals zero.

Matching Functions to Graphs

Matching graphs and their associated algebraic function representations.
