Read this situation : andres is adding molding to the ceiling in his living room. the room is 20 feet long and 12 feet wide. what length of molding does he need?
what do you need to operation do you need to do to manipulate this problem?
area, perimeter, or circumference?

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.

i think the correct option is the second option.
