domain of (x^2-2x-15)+(x+3)

domain

(x^{2} - 2 x - 15) + (x + 3)

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

\frac{5 x - 7}{x ^{3} - 25 x}

x^{3} - 12 x^{2} + 48 x - 68

f (x) = \frac{x ^{3}}{x ^{2} + x - 6}

4 x^{2} - 72

\frac{x ^{2} - 5 x + 2}{x ^{2} + 1}
