In mathematics, the trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. They are widely used in all sciences that are related to geometry, such as navigation, solid mechanics, celestial mechanics, geodesy, and many others.

Mean absolute deviation is a data set is the avg distance in the middle of each data set, so it shows how much they are separated.

The inverse function of f(x) is $f^{-1}(x) = \sqrt{x - 6}$ and the domain is x > 6

<h3>How to determine the inverse function?</h3>

The function is given as:

f(x) = x^2 + 6

Rewrite as:

y = x^2 + 6

Swap x and y

x = y^2 + 6

Subtract 6 from both sides

y^2 = x - 6

Take the square root

$y = \sqrt{x - 6}$

Rewrite as:

$f^{-1}(x) = \sqrt{x - 6}$

Hence, the inverse function of f(x) is $f^{-1}(x) = \sqrt{x - 6}$ and the domain is x > 6
