Help please I’ll give you 25 points
Ira Lisetskai [31]

Answer: Choice D) y = \pm \sqrt{x+5}

The steps to finding the inverse will have us swap x and y. Afterward, we solve for y

y = x^2 - 5 \\\\x = y^2 - 5 \\\\x+5 = y^2 \\\\y^2 = x+5 \\\\y = \pm \sqrt{x+5} \\\\

------------------------------

Extra info:

The inverse relation is not a function because of the plus minus. For instance, plugging x = 4 into y = \pm \sqrt{x+5} leads to y = -3 and y = 3 simultaneously. You would have to apply a domain restriction on y = x^2-5 to make it a one-to-one function, to make the inverse a function. One possible domain restriction is x > 0 which would lead to the inverse function y = \sqrt{x+5}
