The range of f(x)=(6x)/(7x-3) is f(x) 6/7

Popular >

range of f(x)=(6x)/(7x-3)

range

f (x) = \frac{6 x}{7 x - 3}

f (x) < \frac{6}{7} or f (x) > \frac{6}{7}

Interval Notation

(- \infty, \frac{6}{7}) \cup (\frac{6}{7}, \infty)

Solution steps

The function range is the combined domain of the inverse functions

Find the inverse function(s) of:

\frac{6 x}{7 x - 3}

Inverse of

\frac{6 x}{7 x - 3} : \frac{3 x}{7 x - 6}

\frac{3 x}{7 x - 6}

Find the domain of each inverse function

Domain of

\frac{3 x}{7 x - 6} : x < \frac{6}{7} or x > \frac{6}{7}

Combine the intervals

f (x) < \frac{6}{7} or f (x) > \frac{6}{7}

15 x^{\frac{2}{3}} - 10 x

7 x^{6} - 4 x^{5}

f (x) = - 2 x^{3} + 18 x^{2} + 49

f (x) = x^{4} e^{x} - 8

f (x) = \frac{8 x - 6}{x - 3}

What is the range of f(x)=(6x)/(7x-3) ?
The range of f(x)=(6x)/(7x-3) is f(x)< 6/7 \lor f(x)> 6/7
