domain of (x^2-1)/(x^2-49)

domain

\frac{x ^{2} - 1}{x ^{2} - 49}

x < - 7 or - 7 < x < 7 or x > 7

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 7, x = - 7

The function domain

x < - 7 or - 7 < x < 7 or x > 7

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

f (x) = (x + 4)^{3} (x - 3)

f (x) = - 10 z - 5

f (x) = \frac{2 x}{3 x + 8}

f (x) = ln (x^{2} - 25)
