Answer 1

oh gosh O_O this looks ugly >,<
find the points when x = 1 and x=3 for each equation

Answer 2

(0.5, 8)
(-0.5, -8)

Answer 3

hmmm? I don't quite think those are it :P
like f(1) = ? f(3) = ?

Answer 4

oh ok wait

Answer 5

oh gosh nevermind >,< I found a similar way... but you're gonna have to think XP

Answer 6

lol so confused
