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

domain

f (x) = \frac{x + 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

y = 3 - x

f (x) = lo g_{10} (5 x + 35)

f (x) = 5 - t

f (x) = \frac{( x - 1 )}{x ^{2} - 5 x + 6}

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