domain of f(x)=sqrt(4x-42)

domain

f (x) = 4 x - 42

x \geq \frac{21}{2}

Interval Notation

[\frac{21}{2}, \infty)

Solution steps

Find non-negative values for radicals:

x \geq \frac{21}{2}

The function domain

x \geq \frac{21}{2}

y = - \frac{1}{2} x + 3

f (x) = 2 x^{3} - 9 x^{2} - 24 x

f (x) = \frac{x}{x ^{2} - 4}

r (x) = \frac{x ^{3} + 8}{x ^{2} + 4}

\frac{1}{4} (9 x + 3)

What is the domain of f(x)=sqrt(4x-42) ?
The domain of f(x)=sqrt(4x-42) is x>= 21/2
