domain of f(x)= 1/(sqrt(4x-3))

domain

f (x) = \frac{1}{4 x - 3}

x > \frac{3}{4}

Interval Notation

(\frac{3}{4}, \infty)

Solution steps

Find non-negative values for radicals:

x \geq \frac{3}{4}

Find undefined (singularity) points:

x = \frac{3}{4}

Combine real regions and undefined points for final function domain

x > \frac{3}{4}
