You want to know about how long it takes to walk around a circular pond. A:Circumference

A. Circumference

General Formulas and Concepts:

Geometry

Step-by-step explanation:

Since we are walking around the lake and not trying to figure out how much space it is taking up, we would be dealing with circumference in this case.

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.
