Lisa surveyed 60 students at her school and found that 0.85 of the students she surveyed said their favorite class is math. another 15% of the students she surveyed reported that their favorite class is science. how many more students in the survey prefer math over science? 9 15 35 42

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.

what level of math? also i don't need to be paid if i can you.
