Here is a step-by-step method of calculating the value of this function for x = 1:

1. Calculate (x-1)(4x + 1) = (1-1)(4+1) = 0.
2. Divide the answer by 3x = 3, getting 0/3 = 0.
3. Calculate 4x² = 4(1) = 4
4. Add the answers from steps 2 and 3, getting 4 + 0 = 4.

Therefore, the last operation you would perform is addition, showing that the given function is a sum.
