domain of (-x^2+2x+15)/(x+3)

domain

\frac{- x ^{2} + 2 x + 15}{x + 3}

x < - 3 or x > - 3

Interval Notation

(- \infty, - 3) \cup (- 3, \infty)

Solution steps

Find undefined (singularity) points:

x = - 3

The function domain

x < - 3 or x > - 3

ln (\frac{2 + x}{2 - x})

f (x) = \frac{2 cos ( x ) - 1}{sin ( x ) - 1}

f (x) = \frac{1 - ln ( x )}{2 + ln ( x )}

f (x) = 8 + 7 x - 8

2 x^{2} + 3 x - 20
