domain of f(x)=sqrt(x-15)

domain

f (x) = x - 15

x \geq 15

Interval Notation

[15, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 15

The function domain

x \geq 15

f (x) = e^{\frac{x}{4}}

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

f (x) = - 3 + 4 x - 12

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

(x - 1)^{2} (x - 2)^{3}
