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

domain

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

- \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

cos (\frac{θ}{3})

2 - x + 4

f (x) = \frac{1}{8} x - 5

4 x + y - 19 = 0, (6, 3)

y = \frac{5 + x ^{4}}{x ^{2} - x ^{4}}
