domain of y=(2x-7)/(x-3)

domain

y = \frac{2 x - 7}{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

θ

π

- x^{2} + x

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

f (x) = \frac{1 - sin ( x )}{cos ( 2 x )}

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