domain of f(x)=(5x-2)/(sqrt(7x+14))

domain

f (x) = \frac{5 x - 2}{7 x + 14}

x > - 2

Interval Notation

(- 2, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 2

Find undefined (singularity) points:

x = - 2

Combine real regions and undefined points for final function domain

x > - 2

\frac{x - 1}{x ^{2} + 4 x - 5}

- lo g_{5} (x + 2)

f (x) = \frac{2}{x ^{2} - x - 6}

f (x) = \frac{x - 9}{x ^{2} - 3 x}

f (x) = \frac{x ^{2}}{x + 5}
