domain of f(x)=sqrt(-2x-9)

domain

f (x) = - 2 x - 9

x \leq - \frac{9}{2}

Interval Notation

(- \infty, - \frac{9}{2}]

Solution steps

Find non-negative values for radicals:

x \leq - \frac{9}{2}

The function domain

x \leq - \frac{9}{2}

f (x) = - 2 x - 8

f (x) = \frac{- 2 x + 5}{- 3 x + 1}

f (x) = 8 x - 1 + 5 x^{2}

- \frac{1}{2} x

1 + \frac{1}{x}

What is the domain of f(x)=sqrt(-2x-9) ?
The domain of f(x)=sqrt(-2x-9) is x<=-9/2
