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

p er i o d i c i t y - cos (- x) + 4

in v erse y = \frac{x + 2}{x - 3}

a sy m pt o t es f (x) = x^{4} - 4 x^{3}

d o main f (x) = \frac{x + 7}{2 - x}

in v erse f (x) = - x - 5

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