domain of f(x)=sqrt(1-2x)+1/x

domain

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

x < 0 or 0 < x \leq \frac{1}{2}

Interval Notation

(- \infty, 0) \cup (0, \frac{1}{2}]

Solution steps

Find non-negative values for radicals:

x \leq \frac{1}{2}

Find undefined (singularity) points:

x = 0

Combine real regions and undefined points for final function domain

x < 0 or 0 < x \leq \frac{1}{2}

y = - \frac{3}{5} x + 11, (4, - 8)

f (x) = \frac{- x ^{2} + 4}{- 3 x}

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

4.25 cos (6 t) + 5.75

f (x) = \frac{5}{9} (y - 32)
