Hi, https://imgur.com/EjUeSm8 I'm trying to determine the equation for the square root function. Starting point of the graph is at (3,5) pointing down and left and is a square root function. Second point is on (2,4). There seems to be a typo in the explanation in the answer. How do I set up the equation to get radicand as x+3? Thanks

transformations to the parent function $y = \sqrt{x}$ ... reflection over the xaxis $y = \sqrt{x}$ reflection over the yaxis $y = \sqrt{x}$ horizontal shift right 3 units $y = \sqrt{(x3)}$ vertical shift upward 5 units $y = \sqrt{x+3}+5$ graph showing each transformation step attached
