range of (4x+7)/(3x-4)

range

\frac{4 x + 7}{3 x - 4}

f (x) < \frac{4}{3} or f (x) > \frac{4}{3}

Interval Notation

(- \infty, \frac{4}{3}) \cup (\frac{4}{3}, \infty)

Solution steps

The function range is the combined domain of the inverse functions

Find the inverse function(s) of:

\frac{4 x + 7}{3 x - 4}

Inverse of

\frac{4 x + 7}{3 x - 4} : \frac{7 + 4 x}{3 x - 4}

\frac{7 + 4 x}{3 x - 4}

Find the domain of each inverse function

Domain of

\frac{7 + 4 x}{3 x - 4} : x < \frac{4}{3} or x > \frac{4}{3}

Combine the intervals

f (x) < \frac{4}{3} or f (x) > \frac{4}{3}

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

y = - 2 sin (4 x + \frac{π}{2})

ln (x - 5)

f (x) = \frac{1}{2} x^{2} + 4 x + 5

f (x) = 3 x - 6

What is the range of (4x+7)/(3x-4) ?
The range of (4x+7)/(3x-4) is f(x)< 4/3 \lor f(x)> 4/3
