domain of f(x)=sqrt(-2x-1)

domain

f (x) = - 2 x - 1

x \leq - \frac{1}{2}

Interval Notation

(- \infty, - \frac{1}{2}]

Solution steps

Find non-negative values for radicals:

x \leq - \frac{1}{2}

The function domain

x \leq - \frac{1}{2}

f (x) = (3.2)

f (x) = cos (x) - x

f (x) = (x - 2)^{2} + 4

(4, - 8), (8, 5)

f (x) = \frac{6}{x - 1}
