I think its B.

blank · Answer

y = 3x2 + 1 isn't a linear function because it is a parabola.

xximhisgirlxx · Answer

so its C?

xximhisgirlxx · Answer

Can you please help with some more?

blank · Answer

Yeah, the answer is C.

2. Which is NOT true about the following table? https://www.connexus.com/content/media/527934-512012-12037-PM-1450048527.jpg It shows a linear function. x increases by 1 each time. The rate of change is not constant. y increases by a different value each time.

xximhisgirlxx · Answer

I think its D.

blank · Answer

The answer is A. It shows a linear function.

That is because the function is exponential, not linear. :)
