domain of f(x)=((7x+8))/(x-3)

domain

f (x) = \frac{( 7 x + 8 )}{x - 3}

x < 3 or x > 3

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 3

The function domain

x < 3 or x > 3

f (x) = x^{3} - 2 x + 1

f (x) = - 5 + 4 x

x + 3

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

f (x) = 0.6185 x - 9.7758

What is the domain of f(x)=((7x+8))/(x-3) ?
The domain of f(x)=((7x+8))/(x-3) is x<3\lor x>3
