Find the domain of LaTeX:  \displaystyle f(x) = \sqrt{10 x - 13} - 14 . Write the solution in interval notation.

The domain of a radical function is the solution to the inequality radicand LaTeX:  \displaystyle \geq 0 . The inequality is LaTeX:  \displaystyle 10 x - 13 \geq 0 . Isolating LaTeX:  \displaystyle x gives LaTeX:  \displaystyle 10 x \geq 13 Dividing to finish isolating LaTeX:  \displaystyle x gives LaTeX:  \displaystyle x \geq \frac{13}{10} . The domain is LaTeX:  \displaystyle \left[\frac{13}{10}, \infty\right)
