Answer 2

Answer:

The answer is $y=\sqrt{x-5}$.

Step-by-step explanation:

To solve for the inverse of this function, start by writing $f(x)=x^{2} +5$ as an equation, which will look like $y=x^{2} +5$.

Next, interchange the variables, and the equation will look like $x=y^{2}+5$. Then, solve for the y in the equation,

To solve for the y in the equation, rewrite the equation as $y^{2}+5=x$. Next, subtract 5 from both sides of the equation, which will look like $y^{2}=x-5$. The next step is to take the square root of both sides of the equation to eliminate the exponent on the left side, and the equation will look like $y=\sqrt{x-5}$.

To put the answer in actual inverse form, the answer will be $f^{-1} (x)=\sqrt{x-5}$.
