domain of-sqrt(4-x^2)

domain

- 4 - x^{2}

- 2 \leq x \leq 2

Interval Notation

[- 2, 2]

Solution steps

Find non-negative values for radicals:

- 2 \leq x \leq 2

The function domain

- 2 \leq x \leq 2

d o main x + \frac{1}{x}

cr i t i c a l f (x) = \frac{1}{5} x^{4} - \frac{3}{4} x^{4}

a sy m pt o t es f (x) = \frac{5}{( x - 3 ) ^{3}}

d o main f (x) = \frac{2 x - 1}{x - 7}

in f l ec t i o n f (x) = \frac{2 x ^{2}}{x ^{2} - 9}
