domain of (x^2+x-42)/(x^2-x-30)

domain

\frac{x ^{2} + x - 42}{x ^{2} - x - 30}

x < - 5 or - 5 < x < 6 or x > 6

Interval Notation

(- \infty, - 5) \cup (- 5, 6) \cup (6, \infty)

Solution steps

Find undefined (singularity) points:

x = 6, x = - 5

The function domain

x < - 5 or - 5 < x < 6 or x > 6

e^{x + 4} + 7

y = ln (1 - x^{2})

\frac{e ^{x} + sin ( x ) - 1}{ln ( x + 1 )}

f (x) = \frac{1 0 ^{x}}{100000} + 1

f (x) = \frac{1}{1 0 ^{x}}
