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

domain

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

x^{3} + 9 x^{2} - 20 x

f (x) = 2 (2 x - 5) + 3

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

f (x) = \frac{2 x - 1}{2 x ^{2} - 25 x + 63}

ln (x - 1) + ln (x + 2)
