domain of (x^2+5)/(x^2-3x-10)

domain

\frac{x ^{2} + 5}{x ^{2} - 3 x - 10}

x < - 2 or - 2 < x < 5 or x > 5

Interval Notation

(- \infty, - 2) \cup (- 2, 5) \cup (5, \infty)

Solution steps

Find undefined (singularity) points:

x = 5, x = - 2

The function domain

x < - 2 or - 2 < x < 5 or x > 5

\frac{x ^{2} + 10 x + 12}{x ^{2} + 3 x + 2}

\frac{6 x}{x ^{2} - 1}

f (x) = e^{4 x - 7}

f (x) = 3 lo g_{5} (7 x - 4)

f (x) = x^{4} + 8 x^{3} + 16 x^{2}
