Question

Which equation is the inverse of y = x2 – 36?

Answer 1

B. y=±√x+36

Explanation:

The answer to your question is B.

Answer 2

To find the inverse.

`Solve\; x\cdot \:2-36=y \ \textgreater \ \mathrm{Add\:}36\mathrm{\:to\:both\:sides} \ \textgreater \ x\cdot \:2-36+36=y+36`


`\mathrm{Simplify} \ \textgreater \ x\cdot \:2=y+36 \ \textgreater \ \mathrm{Divide\:both\:sides\:by\:}2 \ \textgreater \ (x\cdot \:2)/(2)=(y)/(2)+(36)/(2)`

Simplify again!


`x=(y+36)/(2) \ \textgreater \ \mathrm{Subsititute\:}y=x \ \textgreater \ (x+36)/(2)`


`Therefore\;(x+36)/(2)\;is\;the\;inverse!`

Hope this helps!
