domain of f(x)=sqrt(x-5)+sqrt(x+1)

domain

f (x) = x - 5 + x + 1

x \geq 5

Interval Notation

[5, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 5

The function domain

x \geq 5

f (x) = (\frac{7}{6})^{x}

x x - 1

f (x) = x \cdot (x + 1)

16 y^{2} - 9 x^{2} = 144

f (x) = \frac{9}{3 - 10 x}

What is the domain of f(x)=sqrt(x-5)+sqrt(x+1) ?
The domain of f(x)=sqrt(x-5)+sqrt(x+1) is x>= 5
