domain of f(x)=sqrt(x+20)-1

domain

f (x) = x + 20 - 1

x \geq - 20

Interval Notation

[- 20, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 20

The function domain

x \geq - 20

7 \frac{5}{8}

\frac{x ^{2} - 3}{x ^{2} - 7}

arccsc (\frac{1}{4}) x

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

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