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

domain

f (x) = \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

f (x) = 3 + x + 4

f (x) = 5 x^{2} - 40 x + 61

f (x) = \frac{1}{- 3 x + 1}

f (t) = (arcsin (t)) + ln (t + 1)

8^{x}
