domain of f(x)=(sqrt(20-4x))/2

domain

f (x) = \frac{20 - 4 x}{2}

x \leq 5

Interval Notation

(- \infty, 5]

Solution steps

Find non-negative values for radicals:

x \leq 5

The function domain

x \leq 5

y = \frac{2 x + 14}{x ^{2} - 49}

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

f (x) = \frac{x + 6}{x ^{2} - 4}

(x - 1)^{3}

f (x) = \frac{ln ( x + 5 )}{x ^{2} - 2 x - 3}

What is the domain of f(x)=(sqrt(20-4x))/2 ?
