Hey there,
So the answer is 13.
The explanation is:
We are asked to find f(10), so let's evaluate this function at 10 by plugging this in for x.
So, as we know about the 10, the f(x) is going to be this- f(10).
We put f(10)= 10 over 2 + 8= 5+8 = 13
We have to flip the 8.
So you answer should be 13
Hope this helps...
