domain of arctan(x/(x^2+28))

domain

arctan (\frac{x}{x ^{2} + 28})

- \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) = - x^{2} + 4 x - 4

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

f (x) = - 9 x + 36

h (x) = ln (e^{x} sin (x))

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