Question

What are the excluded values?

Answer 1

Second answer choice: {2,5}

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 2

Answer: B

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
