domain of f(x)=sqrt(5+8x)

domain

f (x) = 5 + 8 x

x \geq - \frac{5}{8}

Interval Notation

[- \frac{5}{8}, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - \frac{5}{8}

The function domain

x \geq - \frac{5}{8}

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

2 x + 3

f (x) = \frac{- 2 x - 8}{5 x + 20}

(- 5, - 3), (9, 8)

y = \frac{1}{4} x + 1

What is the domain of f(x)=sqrt(5+8x) ?
The domain of f(x)=sqrt(5+8x) is x>=-5/8
