domain of f(x)=x+(x^2)/(20)

domain

f (x) = x + \frac{x ^{2}}{20}

- \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 = 0.9 (sin (\frac{π}{3} - x) + 0.01)

f (x) = 1 - x^{3}

f (x) = x e

f (x) = \frac{x + 6}{x - 3}

300 sin (7 t + π)
