Question

I suck at functions. :(

Answer 1

I know domain is all the x values in the function

Answer 2

Possibly (d)?

Answer 3

Trust yourself :D

Answer 4

Everyone who ever did calculus or became a famous physicist or anything that required functions was once a 4 year old kid. 4 year old kids don't know crap about functions. All I'm saying is, there's nothing wrong with being bad, that's why you're in school learning!

I'm happy to inform you that you're right though, you have a pretty solid intuition I think. =D

Answer 5

D has a domain of all real numbers, it would continue on to the left and right forever in both directions. The others all have endpoints.

Answer 6

Oh @agent0smith is right lol
