Did I get these practice questions right?

1. Suppose that f is an even function whose domain is the set of all real numbers. Then which of the following can we claim to be true?

***The function f has an inverse f –1 that is even.

The function f has an inverse f –1, but we can't tell whether it's even or odd.

The function f has an inverse f –1, but we can't tell whether it's even or odd.

f –1 is not a function.

We can't tell whether or not f has an inverse.

2. Suppose that f is an odd function whose domain is the set of all real numbers. Then which of the following can we claim to be true?

(Points : 1)

The function f has an inverse f –1 that is even.

***The function f has an inverse f –1 that is odd.

The function f has an inverse f –1, but we can't tell whether it's even or odd.

The function f does not have an inverse.

We can't tell whether f has an inverse that's still a function.

#1. f^-1 is not a function

Think of y = x^2

every value of y has two values of x.

#2 correct

Hmm... Okay! I see how that works now! :) Thank you so much! I'll be posting a few more problems and would appreciate if you could help with those, too!
