domain of f(x)=(x^2-5)/2

domain

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

- \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 - 1 + 2 x - 4

f (x) = 3^{2 - x} + 1

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

f (x) = 3 5 x + 1

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

What is the domain of f(x)=(x^2-5)/2 ?
The domain of f(x)=(x^2-5)/2 is -infinity <x<infinity
