domain of h(x)=sqrt(x+7)

domain

h (x) = x + 7

x \geq - 7

Interval Notation

[- 7, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 7

The function domain

x \geq - 7

f (x) = - x^{2} + 6

y = - \frac{4}{5} x + 1

y = \frac{x + 2}{x + 8}

\frac{x ^{2} - 25}{x ^{2} - 36}

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