This video tutorial explores the end behavior of power functions, focusing on how the degree and leading coefficient affect the graph's behavior as x approaches positive or negative infinity. It covers four examples: two with even degrees and two with odd degrees, highlighting the differences in graph behavior based on whether the leading coefficient is positive or negative. The video concludes with a summary table to help visualize these concepts.

• It determines the degree of the function.

• It affects the direction of the graph's end behavior.

• It has no effect on the end behavior.

• It only affects the graph's shape, not the end behavior.

Which column should you look at in the summary table if the degree of the power function is odd?

• The column for odd degrees.
