domain of (x^2-1)/(x^2+4)

domain

\frac{x ^{2} - 1}{x ^{2} + 4}

- \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

- lo g_{2} (3 (x - 2)) + 4

f (x) = \frac{8 x ^{2} - 10 x - 3}{2 x ^{2} - 9 x + 9}

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

y = - 2 x - 7
