Question

x -3 -2 -1 0 1 2 3
y 5 -4 -8
Fill in as many y-values as you can if you know that f is a) An even function. b) An odd function

Answer 1

The definition of an even function is that f(-x) = f(x). So, for example, if y(2) (i.e. f(2)) is equal to -8, then y(-2) must be equal to -8.

By contrast, an odd function is a function such that f(-x) = -f(x). So, if y(2) is equal to -8, then y(-2) must be equal to 8.

Answer 2

Same as for when f(-3)=5 then f(3)=-5 ???

Answer 3

yep (if the function is odd).
