domain of f(x)= x/(x^2+81)

domain

f (x) = \frac{x}{x ^{2} + 81}

- \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{3}{2} x - 1, (2, 3)

y = 4 x - 8

f (x) = - \frac{3}{4} x + 12

y = - \frac{7}{2} x - 10, at 7 x - 2 y - 2 = 0

f (x) = 8 - x^{2}
