domain of f(x)=x^2+4x+5

domain

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

- \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{2}{5 - 2 x}

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

\frac{x - 1 - 1}{x - 1 + 1}

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

f (x) = ∣ x + 2 ∣ - 1
