Answer 1

D

Explanation:

A and B cannot be the right answers, because the left part of the graph is inclusive (so the right answer has to include
`x\leq 1` instead of
`x<1`).

C can also not be the right answer, because for
`x=0`,
`y=-1` instead of
`2(0)^2 = 0`.

So D is the correct answer by elimination.
