domain of f(x)=sqrt(\sqrt{x-7)-7}

domain

f (x) = x - 7 - 7

x \geq 56

Interval Notation

[56, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 56

The function domain

x \geq 56

f (x) = 3.1 + 6.6 x - 2.3 x^{2}

\frac{4 x + 7}{3 x - 4}

f (x) = 3 x^{2} + 2 x - 6

y = - 2 sin (4 x + \frac{π}{2})

ln (x - 5)
