domain of x^2+2x+3

domain

x^{2} + 2 x + 3

- \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{x}{2} - 5

f (x) = - x - 4

7 x - 1

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

lo g_{4} (5 x - 9)
