Paper 1Functions & graphsAlgebra

The graph of $y=\sqrt x$ is transformed, in order, first by a translation of $3$ in the positive $x$ -direction and then by a stretch of scale factor $2$ parallel to the $y$ -axis. What is the equation of the resulting graph?

y=2\sqrt x-3

y=\sqrt{2x-3}

y=2\sqrt{x+3}

y=2\sqrt{x-3}

y=\sqrt{2(x-3)}
