domain of f(x)=(x+9)/(x^2+16)

domain

f (x) = \frac{x + 9}{x ^{2} + 16}

- \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

y = - \frac{5}{6 ^{2}} (∣ x ∣ - 17)^{2} + 5

f (x) = - x^{2} + 10 x - 5

f (x) = \frac{1}{( 1 + e ^{- x} )}

f (x) = \frac{x}{( 1 + ∣ x ∣ )}

arcsin (lo g_{10} (\frac{x}{10}))
