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

domain

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

x < 7 or x > 7

Interval Notation

(- \infty, 7) \cup (7, \infty)

Solution steps

Find undefined (singularity) points:

x = 7

The function domain

x < 7 or x > 7

f (x) = arccsch (x)

y = lo g_{3} (x^{2} - 4)

y = - 1 + 9

f (x) = \frac{x ^{2} + 5 x + 6}{x + 4}

f (x) = - lo g_{5} (x - 6) - 3

What is the domain of f(x)=(x(x+2))/(3(x-7)) ?
The domain of f(x)=(x(x+2))/(3(x-7)) is x<7\lor x>7
