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

domain

f (x) = \frac{x ^{2} + 4}{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{3}{1 - 2 x} g (x) = \frac{1}{x}

2^{x + 2} - 2

- tan^{2} (x)

1 - 21 x^{2}

x^{2} + 2 x - 5
