domain of f(x)=-x/(5-2x)

domain

f (x) = - \frac{x}{5 - 2 x}

x < \frac{5}{2} or x > \frac{5}{2}

Solution steps

Find undefined (singularity) points:

x = \frac{5}{2}

The function domain

x < \frac{5}{2} or x > \frac{5}{2}

y = 2 e^{x} + 1

y = x + 3

\frac{x + 4}{4 x ^{2} - 8 x - 12}

f (x) = \frac{x - 4}{x - 10}

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

What is the domain of f(x)=-x/(5-2x) ?
The domain of f(x)=-x/(5-2x) is x< 5/2 \lor x> 5/2
