domain of f(x)=(6x)/(7-x)

domain

f (x) = \frac{6 x}{7 - x}

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) = - x^{2} - 8 x - 7 - 2

y = 5 + 2 e^{x}

x = 11

f (x) = 0.25

y = 2 x^{2} - x - 5

What is the domain of f(x)=(6x)/(7-x) ?
The domain of f(x)=(6x)/(7-x) is x<7\lor x>7
