Consider the function g(x) = |(x^2 - 4)/(x+3)| do the following:

a) Give the domain of the function

b) find the peaks, valleys, and intercepts of the function.



Expert Answer

Step 1

a) First obtain the singularity for the given function as follows.

The denominator of the given fraction is x + 3.

Thus, for x = –3  is the singularity point .

Then the  given function is defined for all values of x except –3.

Therefore, the domain of the given function is 

Step 2

b) From the graph shown below, peak is observed to be the local maximum point.

That is, the peak of the given function is at the point ( -0.76, 1.52).

Valley is a local minimum of the graph.

But here the valleys are at the points (-5.23,10.47), (-2,0) and (2,0).

Thus, the local minimum among those 3 points are (-2,0) and (2,0). 

Step 3

Substitute g(x) = 0 in given equation to...
