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

domain

f (x) = x + 1 + x + 2

x \geq - 1

Interval Notation

[- 1, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 1

The function domain

x \geq - 1

x^{3} + 4

f (x) = \frac{1}{6 2 x + 16 - 12}

f (x) = \frac{4}{x + 10}

f (x) = \frac{5 x}{x ^{2} - 9}

4 x^{2}
