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

domain

y = \frac{x - 2}{- 2 x + 7}

x < \frac{7}{2} or x > \frac{7}{2}

Interval Notation

(- \infty, \frac{7}{2}) \cup (\frac{7}{2}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{7}{2}

The function domain

x < \frac{7}{2} or x > \frac{7}{2}

f (x) = cos (3 x)

(0, - 3), (5, 0)

f (x) = \frac{( x ^{2} - 8 x + 15 )}{x - 5}

f (x) = \frac{1}{x ^{3}}

f (x) = 2 x^{2} + 2 x - 12

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