What is the difference between y=sqrtx +3 and y=2sqrtx +3

(I put spaces between x and the + to show that only the x is a squareroot)

And what is the difference between y=2sqrtx +3 and y=sqrt2x+3

When I mean the difference, I mean how they would look differently when graphed.

Thanks in advance!

one is shifted upward slightly, but they have the same shape.

y=2sqrtx +3 will be slightly shifted upward compared to y=sqrtx +3?
