domain of f(x)=-sqrt(5x+2)-1

domain

f (x) = - 5 x + 2 - 1

x \geq - \frac{2}{5}

Interval Notation

[- \frac{2}{5}, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - \frac{2}{5}

The function domain

x \geq - \frac{2}{5}

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

f (x) = x^{2} - 8 ln (x)

f (x) = \frac{- 18 t ^{2} + 54 t}{t ^{2} + 7 t + 10}

f (x) = \frac{x - 10}{2}

What is the domain of f(x)=-sqrt(5x+2)-1 ?
The domain of f(x)=-sqrt(5x+2)-1 is x>=-2/5
