parity f(x)=(1-e^{1/x})/(1+e^{1/x)}

parity

f (x) = \frac{1 - e ^{\frac{1}{x}}}{1 + e ^{\frac{1}{x}}}

Odd

Solution steps

f (- x) : \frac{1 - e ^{- \frac{1}{x}}}{1 + e ^{- \frac{1}{x}}}

- f (x) : - \frac{1 - e ^{\frac{1}{x}}}{1 + e ^{\frac{1}{x}}}

Check parity of

\frac{1 - e ^{\frac{1}{x}}}{1 + e ^{\frac{1}{x}}}

Check if Even:

False

Check if Odd:

True

Odd

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

(5, 7), (1, 3)

f (x) = \frac{x - 2}{3}

y = 8 x - 5
