• Where the graph crosses the y-axis

• The highest or lowest point of the graph

• Where the graph crosses the x-axis

• The slope of the graph

What happens to the graph of a polynomial function at an x-intercept if its corresponding factor has an odd multiplicity?

• The graph bounces off the x-axis

• The graph goes through the x-axis

• The graph approaches infinity

• The graph has a horizontal asymptote

• It goes through

Organize the steps to complete CYU #2 into the right order.

• use leading term and multiplicity to sketch graph of function

• Factor completely

• set each factor equal to zero

• plot zeros

• determine roots, multiplicity, and graph trait
