domain of (3sqrt(x-13))/(x-13)

domain

\frac{3 x - 13}{x - 13}

x > 13

Interval Notation

(13, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 13

Find undefined (singularity) points:

x = 13

Combine real regions and undefined points for final function domain

x > 13

f (x) = 4 \cdot 2^{x} + 1

f (x) = \frac{11 x ^{2} + x}{x ^{2} + 3}

y = \frac{x}{( x + 4 ) ( x - 9 )}

f (x) = - 0.0005 x^{3} + 60 x

f (x) = - 2 x^{3} - 12 x + 1
