domain of h(x)=sqrt(x+4)

domain

h (x) = x + 4

x \geq - 4

Interval Notation

[- 4, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 4

The function domain

x \geq - 4

f (x) = 7 x + 8

y = 3^{x} - 1

f (z) = 3 z^{2} + 2 z - 4

f (x) = \frac{2 x}{∣ x ∣}

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