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

domain

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

y x^{2} - 4 y - x^{2} = 0

f (x) = x^{4} - x^{3} - 6 x^{2}

y = 5 - 3 x

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

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