Answer:
-5.5
Step-by-step explanation:
Since the left side of the equation says f(5), then plug in 5 for x.
So, it is:
-4|5| + 3
= -20 + 3
= 23
No HAHAHAHAHAahhahahsiaijxjs
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

As we know that Greatest integer is discontinuous at every integer.
So, our Cost function is discontinuous at every integer after x>10.
$7200.. you would find out what 3.5% of $6000 (210) is and then multiply it by 6 (1200) and then add it to the original $6000
