y is the standard graph of sqrtx scaled by sqrt2

Explanation:

y = sqrt(2x)

Remember: sqrt(ab) = sqrta xx sqrtb

:.y = sqrt2 xx sqrtx

Hence, y is the standard graph of sqrtx scaled by sqrt2

This can be seen below by the graphs of y (upper) and sqrtx.

graph{(y-sqrt(2x))(y-sqrtx)=0 [-2.38, 4.548, -0.54, 2.923]}
