domain of f(x)=sqrt(5x-4)

domain

f (x) = 5 x - 4

x \geq \frac{4}{5}

Interval Notation

[\frac{4}{5}, \infty)

Solution steps

Find non-negative values for radicals:

x \geq \frac{4}{5}

The function domain

x \geq \frac{4}{5}

y = - 2 (x - 3)^{2} + 1

y = x^{2} + 4 x + 4

f (x) = x

f (x) = \frac{1 - 4 x}{2 x + 9}

f (x) = 4 + 8 x - 5 x^{2}

What is the domain of f(x)=sqrt(5x-4) ?
The domain of f(x)=sqrt(5x-4) is x>= 4/5
