What is the total length of the race (from point a to point b and point b to point c

if that is the entire question then the answer should be length ac

Step-by-step explanation:

Simple

Step-by-step explanation:

We need the total distance

For that we need to add all points (point a, point b, point c)

Add point a and b point at first then add point c with the answer of point a and b.

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.
