domain of sqrt(x+9)+sqrt(x+8)

domain

x + 9 + x + 8

x \geq - 8

Interval Notation

[- 8, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 8

The function domain

x \geq - 8

(- 3, 2), (2, - 6)

\frac{2 x ^{2} + 4 x - 6}{x ^{2} + 3 x - 10}

f (x) = x - 2 y = 4

f (x) = \frac{x - 4}{x + 4}

2 x^{3} + 1
