Question

Which graph represents y=3√x+2

Answer 1

Adding 2 outside of the third root of x, $y=\sqrt[3]{x}+2$, will shift the regular y=third root of x graph up 2 units.  

Answer: #3

Now if the "+2" is inside the third root, $y=\sqrt[3]{x+2}$, then this will shift the graph left 2 units and the answer would be #2.

It's unclear from the picture if the "+2" is inside or outside the radical.
