Graphing Polynomials • Determine degree • End behavior • Number of Zeros • Turning points • Find the zeros and determine behavior at zero • Find the y-intercept and a few other points
The end behavior of a polynomial function’s graph is the behavior of the graph as x approaches infinity (+ ) or negative infinity (– ). The expression x+ is read as “x approaches positive infinity.” END BEHAVIOR
What we already know • Think about the end behavior of the following
Let’s Explore • Consider the following functions. • Degree 3 • Leading Coefficient 1 • Degree 3 • Leading Coefficient -2
Let’s Explore • Consider the following functions. • Degree 4 • Leading Coefficient -3 • Degree 4 • Leading Coefficient1
CONCEPT END BEHAVIOR FOR POLYNOMIAL FUNCTIONS SUMMARY LCdegx – x + > 0 even f(x) + f(x) + > 0 odd f(x) – f(x) + < 0 even f(x) – f(x) – < 0 odd f(x) + f(x) – END BEHAVIOR
