Well, function is already written in "function notation" though not explicitly which I assume is "function notation".
Explicit notation for this function is:

Hope this helps.
The surface area of the cone is 
Explanation:
The diameter of the cone is 10 cms
Thus, the radius of the cone is given by

The slant height of the cone is 12 cms
The formula for surface area of the cone is given by

Substituting the values, we get,




Thus, The surface area of the cone is 
Answer:
f(-2) = 1.
Step-by-step explanation:
If we are solving for f(-2), we will simply need to substitute in '-2' for 'x'. This gives us:
f(-2) = -2 + 3
f(-2) = 1.
Markup =35%
Model train cost =100
So 135%=100
1%=100/135
100%=100/35)*100=74.07
Original cost =74.07
