domain of f(x)= 1/(sqrt(5.7x-8.1x^2))

domain

f (x) = \frac{1}{5.7 x - 8.1 x ^{2}}

0 < x < \frac{19}{27}

Interval Notation

(0, \frac{19}{27})

Solution steps

Find non-negative values for radicals:

0 \leq x \leq \frac{19}{27}

Find undefined (singularity) points:

x = 0, x = \frac{19}{27}

Combine real regions and undefined points for final function domain

0 < x < \frac{19}{27}
