Find the inverse of the function:<br> y=log₂(-4x)

Vlad1618 [11]

Answer:

-2^(x-2)

Step-by-step explanation:

Using differential calculus:

We know that the integral of 1/x = ln(x)

or 2x/ln(2) = log2(x), so we plug in our knowledge and chain rule to figure out that the answer to the inverse is -2^(x-2) :)

A long distance phone service charges $0.30 for the first 10 minutes and $0.05 for each additional minute or fraction thereof. U

olga nikolaevna [1]

Answer: Our Cost function is discontinuous at every integer after x>10.

Step-by-step explanation:

Since we have given that

For the first 10 minutes , the service charges = $0.30

Let the number of additional minute be 't'.

Amount charge for each additional minute = $0.05

Using the greatest integer function:

So, Cost C of a call in terms of time 't' minutes would be

$C=0.03+0.05\left \lceil t-10 \right \rceil$

As we know that Greatest integer is discontinuous at every integer.

So, our Cost function is discontinuous at every integer after x>10.
