Function. Degree X-intercepts Zeros Number of Zeros 2 (0,0) (4,0) 0 and 4 2 These x-intercepts are called the zeros of the polynomial functions. Why do you think they have this name? Fill in the column labeled “Zeroes” by writing the zeroes that correspond to the x-intercepts of each polynomial function, and also record the number of zeroes ...

You must be able to find zeros of functions, find asymptotes of functions, find the intersection of functions, the max and min of functions, and appropriately adjust your window size as needed. In general, you should be able to sketch out the graph of any reasonable function given to you. Here's some general guidelines: 1) Plot a few sample points.

Explain how the use of the Zero function from the CALC menu determined the x-intercepts of the functions listed above. There are several ways to find the x-intercepts of a function with the use of the grapher. One method is to use the CALC, 2:zero method. Another way is to use the Polynomial Root Finder in the POLYSMLT APP.

We have found that the zeros of the denominator of a rational function are the vertical asymptotes of the function. The zeros of the numerator on the other hand, are the x intercepts of the function. Find all x and y intercepts of the function. Write out the function in completely factored form. Now, find the zeros …

Find the zeros of the function by solving Any real zeros are the first coordinates of the x-intercepts. Use the zeros (x-intercepts) to divide the x-axis into intervals and choose a test point in each interval to determine the sign of all function values in that interval. Find This gives the y-intercept of the function.
