I think it's C

Answer 1

its E

Answer 2

I'm just kidding, i think u are correct tho

Answer 3

Answer 4

The vertical line test must only cross the curve one place for each x value.

Answer 5

the first three are correct

Answer 6

all piecewise functions are functions, and all functions pass the vertical line test.
