Where represents cars. This function models the profits they make.
Now, as you can deduct already, we can define to different domains, the mathematical one and the reasonable one.
The reasonable domain is about all the useful values to the problem. For example, as we are talking about car, they can't wash -5 cars, so negative numbers are excluded. Similarly, they can't wash 6.75 cars, because that would imply an incomplete job.
Therefore, the domain for this function is where
.
(Notice that we specify that the independent valur can only use whole positive numbers only).
First of all, a meter is equal to 100cm.
Seb made a jump of two and a half meters. (
or 
)
Multiply 100 by 2.
Now we need the half.
What is half of 100?
50 is half of 100.
So, add 50 to the 200.
Kirsty's jump was 10 centimeters longer.
Add 10 centimeters to the 250 centimeters.
Kirsty's jump was 260 centimeters high, or 2.55 meters.
