domain of f(x)=sqrt(x-3)-sqrt(x+3)

domain

f (x) = x - 3 - x + 3

x \geq 3

Interval Notation

[3, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 3

The function domain

x \geq 3

2 y - 2 x = 8

\frac{x ^{3} + 8}{x ^{2} + 4}

y = \frac{2}{10} x + \frac{8}{10}, (1, 1)

f (x) = x^{\frac{1}{3}}

f (x) = 8 x + 7
