The “1” in the last row of the synthetic division represents the remainder of the division of the polynomial \(-x^3 + 3x^2 - 2x + 7\) by \(x - 3\).
In synthetic division, the last entry in the bottom row is the remainder when the polynomial is divided by the linear divisor.
So, the correct interpretation is:
The remainder is 1.
