domain of (x+3)/(x^2-16)

domain

\frac{x + 3}{x ^{2} - 16}

x < - 4 or - 4 < x < 4 or x > 4

Solution steps

Find undefined (singularity) points:

x = 4, x = - 4

The function domain

x < - 4 or - 4 < x < 4 or x > 4

\frac{2 x + 9}{7 x}

\frac{5 x ^{2} + 1}{ln ( 2 ) x ( 5 x ^{2} + 3 )}

f (x) = \frac{5}{3}

\frac{2 x}{x - 7}

f (x) = lo g_{10} (5 - x)
