Answer:

Second answer choice:  {2,5}

Step-by-step explanation:

2 and 5 are the excluded values of b here.  That's because at either b = 2 or b = 10, we have division by zero in this rational function.

Answer: B

Step-by-step explanation:

the denominator canNOT equal zero.

b² - 7b + 10 ≠ 0

(b - 2)(b - 5) ≠ 0

b - 2 ≠ 0    and     b - 5 ≠ 0

  +2  +2                  +5   +5

b      ≠ 2     and    b       ≠ 5

So, the excluded values are when b = 2 and b = 5
