domain of (x^2-13x+36)/(x^2+25)

domain

\frac{x ^{2} - 13 x + 36}{x ^{2} + 25}

- \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

f (x) = \frac{x ^{2} - 36}{x ^{2} - 25}

\frac{( 6 + x ) ( 3 + x )}{- 3 - 4 x}

- 3.3

f (x) = \frac{6}{25 - x ^{2}}

6 x^{2} - 15 x
