As
29. odd and even functions derivative problem a
function is called an odd function if it has the
property f(-x)=-f(x). similarly, f is called an
even function iff-x) = rx). for instance,
sire is odd because sin (-x) = -sin x, and
cosine is even because cos (-x) = cos x. use the
chain rule appropriately to prove that the
derivative of an odd function is an even
function and that the derivative of an even
function is an odd function.

Stu and ambrose are working together on a study of whether diet is related to students' mental health. first, they randomly select 10 students from the student center and 10 students from the office of counseling and psychological services. then, they ask students to rate their diet in terms of healthiness on a scale of 1-100 before completing a 20-item mental health survey. a) name one of the constructs being studied b) how was the construct you named above operationally defined in this experiment? e) was the variable you described above their independent variable, their dependent variable, or a controlled variable? d) what is a confounding variable? what is a potential confound in this study?
