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
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
