domain of f(x)=(2x)/(sqrt(x+1))

domain

f (x) = \frac{2 x}{x + 1}

x > - 1

Interval Notation

(- 1, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 1

Find undefined (singularity) points:

x = - 1

Combine real regions and undefined points for final function domain

x > - 1

e^{x}

f (x) = - 9 x + 54

y = x + 2

\frac{2 - x}{x ^{2} + 4 x - 32}

\frac{5}{7}
