range of (7+5x)/(4x-5)

range

\frac{7 + 5 x}{4 x - 5}

f (x) < \frac{5}{4} or f (x) > \frac{5}{4}

Interval Notation

(- \infty, \frac{5}{4}) \cup (\frac{5}{4}, \infty)

Solution steps

The function range is the combined domain of the inverse functions

Find the inverse function(s) of:

\frac{7 + 5 x}{4 x - 5}

Inverse of

\frac{7 + 5 x}{4 x - 5} : \frac{7 + 5 x}{4 x - 5}

\frac{7 + 5 x}{4 x - 5}

Find the domain of each inverse function

Domain of

\frac{7 + 5 x}{4 x - 5} : x < \frac{5}{4} or x > \frac{5}{4}

Combine the intervals

f (x) < \frac{5}{4} or f (x) > \frac{5}{4}

y = x^{\frac{1}{2}}

ln (2 - 5 x^{2})

m = - \frac{2}{3} (0.6)

2 x^{3} + 6 x^{2} - 18 x + 5

y = - 10

What is the range of (7+5x)/(4x-5) ?
The range of (7+5x)/(4x-5) is f(x)< 5/4 \lor f(x)> 5/4
