Write a function rule`f` that gives the total cost of apples in terms of the number of pounds, `x`.
Number of pounds (x) 0,1,2,6,10,x
The function `f` that gives the total cost of apples in terms of the number of pounds, `x`, can be represented as:
f(x) = 1.25 * x
This function calculates the total cost by multiplying the number of pounds, `x`, by the cost per pound, which is $1.25.
