domain of f(x)= 4/(sqrt(x))+7

domain

f (x) = \frac{4}{x} + 7

x > 0

Interval Notation

(0, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 0

Find undefined (singularity) points:

x = 0

Combine real regions and undefined points for final function domain

x > 0

\frac{x ^{2} - 6 x + 12}{x - 4}

- cos (- x) + 4

y = \frac{x + 2}{x - 3}

f (x) = e^{x - 1}

f (x) = \frac{5}{x + 4}

What is the domain of f(x)= 4/(sqrt(x))+7 ?
The domain of f(x)= 4/(sqrt(x))+7 is x>0
