domain of f(x)=sqrt(-4-2x-3)

domain

f (x) = - 4 - 2 x - 3

x \leq - \frac{7}{2}

Interval Notation

(- \infty, - \frac{7}{2}]

Solution steps

Find non-negative values for radicals:

x \leq - \frac{7}{2}

The function domain

x \leq - \frac{7}{2}

y = x^{3} + 2 x^{2}

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

f (x) = \frac{x + 4}{x ^{2} - 1}

\frac{4}{2 x - 3}

f (x) = sin (6 x)
