A. For what value of y is the expression 12÷(y-2) undefined?________
B. Briefly explain why the expression is undefined for the value you noted in A.
:
Write it
12%2F%28y-2%29
An expression is undefined when the denominator = 0
therefore to find the value of y for this to occur
y - 2 = 0
y = +2
:
Expression is undefined when y = 2
:
Make sense?
