domain of f(x)=sqrt(5x-20)

domain

f (x) = 5 x - 20

x \geq 4

Interval Notation

[4, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 4

The function domain

x \geq 4

f (x) = 2 (\frac{1}{2} x - \frac{1}{6}) + \frac{1}{3}

f (x) = - 4^{x}

f (x) = \frac{1}{7} (9)^{x}

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

\frac{1}{e ^{x} - 1}

What is the domain of f(x)=sqrt(5x-20) ?
The domain of f(x)=sqrt(5x-20) is x>= 4
