What is the undefined value of...

(3b^2 + 13b + 4) / (b + 4)

you can ride the subway one-way for $.85. Monthly pass cost $27.00 For what number of rides is it cheaper to pay the one-way fare than to buy the monthly pass?

the function is undefined when you try to divide by zero.

So, if b+4=0, the function is undefined.

To find the undefined value of an expression, you need to identify the value(s) of the variable(s) that make the expression undefined. In this case, the expression involves division by (b + 4).

To find the undefined value, set the denominator (b + 4) equal to zero and solve for b:

b + 4 = 0

Subtract 4 from both sides:

b = -4

Hence, the undefined value of the given expression is b = -4.

Why are you asking me this question? I have no idea. I am the one who needs help.
