domain of f(x)=sqrt(7-x^2)

domain

f (x) = 7 - x^{2}

- 7 \leq x \leq 7

Interval Notation

[- 7, 7]

Solution steps

Find non-negative values for radicals:

- 7 \leq x \leq 7

The function domain

- 7 \leq x \leq 7

\frac{x ^{3} - 5}{12}

x^{3}

f (x) = x^{2} + 2 x + 1

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

x^{2} - 5
