domain of R(n)=(n+1)/(n^2-6n+8)

domain

R (n) = \frac{n + 1}{n ^{2} - 6 n + 8}

n < 2 or 2 < n < 4 or n > 4

Interval Notation

(- \infty, 2) \cup (2, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

n = 4, n = 2

The function domain

n < 2 or 2 < n < 4 or n > 4

9 - 25 x^{2}

f (x) = 8 - 2 x^{2}

\frac{6}{x - 9}

f (x) = lo g_{10} (2 x + 3)

arcsin (e^{x})
