WebExample: How about this piecewise function: It looks like this: It is defined at x=1, because h(1)=2 (no "hole") But at x=1 you can't say what the limit is, because there are two competing answers: "2" from the left, and "1" from the right; so in fact the limit does not exist at x=1 (there is a "jump") And so the function is not continuous. Web20 de dez. de 2024 · To find the zeros of a polynomial function, if it can be factored, factor the function and set each factor equal to zero. Another way to find the x-intercepts of a polynomial function is to graph the function and identify the points at which the graph crosses the x-axis.
