domain of f(x)=sqrt(1-4x)

domain

f (x) = 1 - 4 x

x \leq \frac{1}{4}

Interval Notation

(- \infty, \frac{1}{4}]

Solution steps

Find non-negative values for radicals:

x \leq \frac{1}{4}

The function domain

x \leq \frac{1}{4}

\frac{( 2 x ^{2} + x )}{x ^{3} + 8 x ^{2} + 15 x}

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

y = 1 - cos (x)

(21, - 30), (3, 8)

y = 1 - x^{2}
