domain of f(x)=\sqrt[4]{3x-21}

domain

x \geq 7

Interval Notation

[7, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 7

The function domain

x \geq 7

f (t) = \frac{1}{t + 1} + \frac{t}{2} - 3 t

f (x) = \frac{9}{7 x - 28}

g (x) = \frac{1}{x - 2}

f (x) = x^{2} + 3 x - 1

y = 2 x + 1
