domain of f(x)=(x+8)/(x^2-16x+64)

domain

f (x) = \frac{x + 8}{x ^{2} - 16 x + 64}

x < 8 or x > 8

Interval Notation

(- \infty, 8) \cup (8, \infty)

Solution steps

Find undefined (singularity) points:

x = 8

The function domain

x < 8 or x > 8

f (x) = 3 - 2 x

y = (x + 4)^{2}

y - 6 = 0, (- 2, 5)

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

f (x) = y - 14

What is the domain of f(x)=(x+8)/(x^2-16x+64) ?
The domain of f(x)=(x+8)/(x^2-16x+64) is x<8\lor x>8
