domain of f(x)=3x-2/(sqrt(x+1))

domain

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

sin^{2} (x)

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

y = 3 sin (\frac{x}{2} \frac{- π}{3})

f (x) = (x - 3) (x + 2)

y = - (x + 3)^{2} - 1
