range of f(x)= 7/2 e^{-2x^2}

range

0 < f (x) \leq \frac{7}{2}

Interval Notation

Solution steps

The function range is the combined domain of the inverse functions

Find the inverse function(s) of:

\frac{7}{2} e^{- 2 x^{2}}

Inverse of

\frac{7}{2} e^{- 2 x^{2}} : - \frac{ln ( \frac{2 x}{7} )}{2}, - - \frac{ln ( \frac{2 x}{7} )}{2}

- \frac{ln ( \frac{2 x}{7} )}{2}, - - \frac{ln ( \frac{2 x}{7} )}{2}

Find the domain of each inverse function

Domain of

- \frac{ln ( \frac{2 x}{7} )}{2} : 0 < x \leq \frac{7}{2}

Domain of

- - \frac{ln ( \frac{2 x}{7} )}{2} : 0 < x \leq \frac{7}{2}

Combine the intervals

0 < f (x) \leq \frac{7}{2}

What is the range of f(x)= 7/2 e^{-2x^2} ?
The range of f(x)= 7/2 e^{-2x^2} is 0<f(x)<= 7/2
