domain of f(x)=sqrt(9+8x)

domain

f (x) = 9 + 8 x

x \geq - \frac{9}{8}

Interval Notation

[- \frac{9}{8}, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - \frac{9}{8}

The function domain

x \geq - \frac{9}{8}

f (x) = 5 x^{3} - 60 x^{2} + 12 x + 99

f (x) = \frac{2 x + 5}{- 3 x + 9}

y = 9 x

x^{2} - 5 x + 2

f (x) = x e^{- x}

What is the domain of f(x)=sqrt(9+8x) ?
The domain of f(x)=sqrt(9+8x) is x>=-9/8
