Question

Given the graph of y=f(x)

1. y = (-f)
**I think this is that you reflect across the x-axis.

2. y = f(-x) = f(x) even
I'm not sure.

3. y = -f(x) = f(-x) odd
Not sure either.

Answer 1

1. -f is the reflection of f about the x-axis.
2. f(-x)=f(x) => f(x) is even
3. f(-x)=-f(x) => f(x) is odd

Good job! :)
