domain of f(x)= 3/(sqrt(x-1))

domain

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

x > 1

Interval Notation

(1, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 1

Find undefined (singularity) points:

x = 1

Combine real regions and undefined points for final function domain

x > 1

- (x + 1)^{2} + 1

f (x) = \frac{x + 5}{x + 6}

y = \frac{x - 2}{1 - x ^{2}}

f (x) = e^{x} + 6

f (x) = \frac{5}{x ^{2} ( x - 4 )}
