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

domain

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

- \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) = 0.5 x

cos (6 x)

f (x) = \frac{( x ^{2} - 1 )}{2 x - 3}

f (x) = \frac{x ^{2} + 3 x}{x ^{2} - x}

f (x) = - - \frac{10 x - 458}{49} - 3
