domain of f(x)=(x-2)/(x+7)

domain

f (x) = \frac{x - 2}{x + 7}

x < - 7 or x > - 7

Interval Notation

(- \infty, - 7) \cup (- 7, \infty)

Solution steps

Find undefined (singularity) points:

x = - 7

The function domain

x < - 7 or x > - 7

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

f (x) = - x^{\frac{1}{2}} + 5

f (x) = \frac{1 - 5 x}{4 + x}

y = 6 x + 3
