Answer:
±[tex]\sqrt{x+36} \\[/tex]
Step-by-step explanation:
If you question is inverse of y = [tex]x^{2}[/tex] - 36, then this is the answer. First, you need to switch the x and y, then make x the subject. Steps:
[tex]x=y^{2} -36[/tex]
[tex]=>x+36=y^{2}[/tex]
[tex]=>y=\sqrt{x+36}[/tex]
That's it. Hope it helped.
