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

domain

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

f (x) = 9 x - 3

5.75 cos (\frac{π}{3} t) + 7.88

f (x) = - x^{2} + 7 x

y + 4 = x^{\frac{2}{3}}

\frac{x ^{2} - 3 x + 2}{x ^{2} + 7 x + 12}
