domain of sqrt(121-x^2)

domain

121 - x^{2}

- 11 \leq x \leq 11

Interval Notation

[- 11, 11]

Solution steps

Find non-negative values for radicals:

- 11 \leq x \leq 11

The function domain

- 11 \leq x \leq 11

f (x) = \frac{x - 4}{x + 8}

\frac{t - 5}{t ^{2} + 2 t - 15}

f (x) = 2 x + 5, 0 \leq x \leq 2

- 2 x^{2} + 2 x

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