PLEASE HELP!! ITS IN MATH

A, 12%

Step-by-step explanation:

There are 25 people who answered the survey. Out of 25 students, 3 people were in a household of 7 and 8.

so 3/25, which is 12 percent

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 it might be a but you might want a second opinion
