range of 7/(2x-10)

range

\frac{7}{2 x - 10}

f (x) < 0 or f (x) > 0

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

The function range is the combined domain of the inverse functions

Find the inverse function(s) of:

\frac{7}{2 x - 10}

Inverse of

\frac{7}{2 x - 10} : \frac{7 + 10 x}{2 x}

\frac{7 + 10 x}{2 x}

Find the domain of each inverse function

Domain of

\frac{7 + 10 x}{2 x} : x < 0 or x > 0

Combine the intervals

f (x) < 0 or f (x) > 0

x^{3} - 8 x^{2} - 12 x + 3

y = \frac{1}{4} x + 1, (- 2, 1)

\frac{x - 2}{x - 4}

(0, 7), (7, 3)

x + \frac{1}{x}
