range of 2/(x^2)+9

range

\frac{2}{x ^{2}} + 9

f (x) > 9

Interval Notation

(9, \infty)

Solution steps

The function range is the combined domain of the inverse functions

Find the inverse function(s) of:

\frac{2}{x ^{2}} + 9

Inverse of

\frac{2}{x ^{2}} + 9 : \frac{2}{x - 9}, - \frac{2}{x - 9}

\frac{2}{x - 9}, - \frac{2}{x - 9}

Find the domain of each inverse function

Domain of

\frac{2}{x - 9} : x > 9

Domain of

- \frac{2}{x - 9} : x > 9

Combine the intervals

f (x) > 9

12 x + 4 y = 24

f (x) = \frac{1}{x - 5}

- 3 tan (\frac{1}{2} x)

\frac{x ^{2} - 3 x - 18}{x - 10}

\frac{1}{6 - x}
