domain of (x^2-8x+15)/(x^2-7x+12)

domain

\frac{x ^{2} - 8 x + 15}{x ^{2} - 7 x + 12}

x < 3 or 3 < x < 4 or x > 4

Interval Notation

(- \infty, 3) \cup (3, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = 4, x = 3

The function domain

x < 3 or 3 < x < 4 or x > 4

f (x) = - 4 - x

f (x) = \frac{x ^{2} - 6 x + 8}{x - 4}

- lo g_{2} (x - 1)

\frac{5 x}{x - 2}

y = 2 x - ∣ 4 - x ∣
