Question

4. What is the undefined value of 3b^2+13b+4/b+4? (1 point)

Answer 1

You can't divide by zero. So the denominator can't be equal to zero.


If it were, then b + 4 =0, solve for b

b+4 = 0

b+4-4 = 0-4

b = -4


So if b = -4, then the denominator is zero, which makes the entire expression undefined.
