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

domain

f (x) = \frac{x ^{2} - 4}{x ^{2} + 1}

- \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

x^{2} - 6 x + 8

y = \frac{4}{3} x + 7 - 5

\frac{5 x}{8 x - 1}

f (x) = \frac{- 2 x + 5}{3}

f (x) = \frac{x + 7}{x - 7}

What is the domain of f(x)=(x^2-4)/(x^2+1) ?
The domain of f(x)=(x^2-4)/(x^2+1) is -infinity <x<infinity
