1. last week, kari ran 3.4 miles on monday,
3.9 miles on thursday, and 6.8 miles on
saturday. did kari run more than 15 miles
last week?

No, Kari did not run more than 15 miles last week, she instead only ran 14.1 miles. Hope this helps :)

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.
