domain of sqrt(x^2+5x+4)

domain

x^{2} + 5 x + 4

x \leq - 4 or x \geq - 1

Interval Notation

(- \infty, - 4] \cup [- 1, \infty)

Solution steps

Find non-negative values for radicals:

x \leq - 4 or x \geq - 1

The function domain

x \leq - 4 or x \geq - 1

f (x) = \frac{sin ( x )}{cos ( x )}

f (x) = \frac{x - 3}{x ^{2} - 4} ln (x)

- \frac{6}{x ^{2}}

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

f (x) = tan (\frac{1}{2} x)

What is the domain of sqrt(x^2+5x+4) ?
The domain of sqrt(x^2+5x+4) is x<=-4\lor x>=-1
