Pamela wants to learn more about the career preferences of students in her school. she interviews a number of students from the advanced science classes. why is this sample likely to be biased?

a. advanced science students may not have clear career preferences.

b. the numbers of boys and girls in the advanced science classes are not equal.

c. advanced science students are not representative of all the students in the
school.

d. it is too early for students to have career preferences while still in school.

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.

add the table and i will answer correctly
