Quizplus · Accepted Answer

The given polynomial has a degree of 1 (linear polynomial) as the exponent of $x$ is 1. Therefore, the constant term is the $x^0$ term, which is just a number. To find it, we can set $x=0$ in the polynomial and simplify: $11eb0d3b\_976a\_7541\_9790\_f560def2f8d4_{TB1243\_11} = -9 \cdot 0 + 4 = 4$. Thus, the constant term is 4. To find $11eb0d3b\_976a\_7542\_9790\_17e6a7016429_{TB1243\_11}$, we can set $x=-1$ and simplify: $11eb0d3b\_976a\_7541\_9790\_f560def2f8d4_{TB1243\_11} = -9 \cdot (-1) + 4 = 11$. Therefore, the answer is (B) 11.
