Michael and Tracy are carpeting their family room that is 15 1/2 feet long and 12 1/4 feet wide. To find the amount of carpet needed, Michael says to multiply 15 1/2 and 12 1/4 and Tracy says to multiply 12 1/4 and 15 1/2. Who is right? How much carpet is needed?

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
