domain of f(x)= 3/(sqrt(x-7))

domain

f (x) = \frac{3}{x - 7}

x > 7

Interval Notation

(7, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 7

Find undefined (singularity) points:

x = 7

Combine real regions and undefined points for final function domain

x > 7

- 3 x^{2} + 12 x - 7

f (x) = 5 - x

y = lo g_{2} (x + 2)

\frac{2 x + 1}{2 x - 6}

h (z) = \frac{z + 4}{z - 2}
