Question

Where is the function increasing? equation below

Answer 1

\[f(x)=\frac{ x-4 }{ 2x-6 }\]

Answer 2

Find the critical numbers then test all intervals to the left and right of these values.

Answer 3

I don't know how to do that...

Answer 4

To find the critical numbers, take the derivation of the function then set it equal to zero then find the value of x.

Answer 5

How to do that?

Answer 6

derivative*

Just use Quotient Rule to take the derivative of function.

Answer 7

okay! Thank you
