Answer 1

Just graph it... Firstly though, do you know what a function is?
Google linear function, parabolic function, exponential function etc. to get familiar with what a function looks like.

Firstly, no function that I know has
(4, 5) and (4, -4) where there are two y coordinates for 1 x coordinate.
It is not linear, parabolic, or exponential, it could be some other type of function. But assuming you're in high school i'd say its safe to bet the answer is FALSE.
