Question

Given the function f(x)=x^2-81/x^2-11x+18 on your graphing calculator, what is the most appropriate viewing window to see the graph?

Answer 1

We have been given a rational function:

`f(x)=(x^2-81)/(x^(2)-11x+18)`

And we are required to determine an appropriate viewing rectangle for the graphing calculator.

An appropriate viewing rectangle is the set of minimum and maximum values of x and y on which all important attributes of the graph are clearly displayed.

For the given function, an appropriate viewing rectangle will be [-20,20,2] by [-20,20,2].

This function, when graphed using a graphing calculator on the said viewing rectangle, it appears as attached.

Answer 2
