Question

f(x)=-|-8t|+|-7t|. determine whether odd or even

Answer 1

An even function looks even, that it, it looks symmetrical. So the left side is equal to the right side. That is, for any x, f(x)=f(-x).

An odd function has the right side opposite sign as the left side. That is, for any x, f(x) = -f(-x).

You can see which of these definitions your function satisfied by plugging -x into the function, and seeing if you end up with f(x) or -f(x).

Answer 2

how can the answer be even? i do't get it? it is because of the absolute values right?
