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

domain

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

x < 4

Interval Notation

(- \infty, 4)

Solution steps

Find non-negative values for radicals:

x \leq 4

Find undefined (singularity) points:

x = 4

Combine real regions and undefined points for final function domain

x < 4

\frac{( x + 5 )}{x ^{2} - 25}

f (x) = (x - 4)^{3}

f (x) = (x)

x 2 - x^{2}

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