Answer:
The value of f(3) is -2.
Step-by-step explanation:
This is a recursive function. So

Now, we find f(2) in function of f(1). So


Now, with f(2), we can find the value of f(3).


The value of f(3) is -2.
the median out of the data set is.
<u><em>12.</em></u>
to find the median, you have to,
The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middle-most numbers.


Using hit and trial, you van find it pretty easily-
- Putting x=0, we get y=-3
- Putting x=1, we get y=-1
- Putting x=2, we get y=5
You can try it for yourself as well, for me, I couldn't find any other option appropriate.
