parity sqrt((1+cos(x))/(1-cos(x)))

parity

\frac{1 + cos ( x )}{1 - cos ( x )}

Even

Solution steps

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

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

Check parity of

\frac{1 + cos ( x )}{1 - cos ( x )}

Check if Even:

True

Check if Odd:

False

Even

y

f (x) = (x + 2)^{(\frac{1}{3})}

f (x) = lo g_{8} (3 x + 2)

f (x) = 5 x - 25

3 x - 5 y = - 15
