domain of f(x)=(x+2)/(sqrt(x-10))

domain

f (x) = \frac{x + 2}{x - 10}

x > 10

Interval Notation

(10, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 10

Find undefined (singularity) points:

x = 10

Combine real regions and undefined points for final function domain

x > 10

f (x) = 6 cos (3 x - \frac{π}{4})

f (x) = x + 7 + 2

f (x) = x^{3} - 6 x
