1. Esmeralda and Heinz are working to graph a polynomial function, f(x). Esmeralda says that the third-degree polynomial has four intercepts. Heinz argues that the function only crosses the x-axis three times. Is there a way for them both to be correct? Explain your answer. :/

    It helps to know what the words mean: Intercept: where the curve/line crosses the x- or the y-axis. "crosses the x-axis" = x-intercept Read more about it at: http://www.purplemath.com/modules/intrcept.htm

    Reread: "It helps to know what the words mean: Intercept: where the curve/line crosses the x- or the y-axis. "crosses the x-axis" = x-intercept" |dw:1433778077452:dw| The above drawing shows a third degree curve. Count the number of intercepts, and the number of times it crosses the x-axis.

    There should be two answers to: "Count the number of intercepts, and the number of times it crosses the x-axis", or 1. Count the number of intercepts, and 2. Count the number of times it crosses the x-axis.

    4 Intercepts it crosses the x-axis 3 times right?

    Correct, so reread the question and then explain to the best of your capacity.

    Ok ok xD hmm so it is possible because intercepts and crossing the x axis are two different things?
