domain of (x^2+x-30)/(x^2-x-20)

domain

\frac{x ^{2} + x - 30}{x ^{2} - x - 20}

x < - 4 or - 4 < x < 5 or x > 5

Interval Notation

(- \infty, - 4) \cup (- 4, 5) \cup (5, \infty)

Solution steps

Find undefined (singularity) points:

x = 5, x = - 4

The function domain

x < - 4 or - 4 < x < 5 or x > 5

\frac{1}{3} lo g_{10} (3 x)

f (x) = \frac{2 x - 8}{5}

- (\frac{( 3 )}{( 4 )}) x + 2

250342 e^{0.012 t}

y = \frac{2 x - 18}{x ^{2} - 18 x}
