Well, since she makes 5 cards in ONE hour, we'll just multiply 5 times 6 to find out the total amount of cards made in 6 hours, which is 30.

when it comes to checking if a function is even or odd, it boils down to changing the argument, namely x = -x, and if the <u>resulting function is the same as the original</u>, then is even, if the <u>resulting function is the same as the original but negative</u>, is odd, if neither, well then neither :).
anyway, that said, let's first expand it and then plug in -x,
