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

domain

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

f (x) = 2^{1 - x^{2}}

f (x) = \frac{x + 1}{x ^{2} + 5 x + 4}

y = - 3 (x - 2)^{2} + 4

\frac{8 x + 3}{2 x - 6}

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