domain of f(x)=7+2/(3-x)

domain

f (x) = 7 + \frac{2}{3 - x}

x < 3 or x > 3

Interval Notation

(- \infty, 3) \cup (3, \infty)

Solution steps

Find undefined (singularity) points:

x = 3

The function domain

x < 3 or x > 3

\frac{x ^{2}}{x ^{2} - 1}

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

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

y = x^{2} \cdot ln (\frac{x}{8})
