Answer:
C. -3
Step-by-step explanation:
Since division by zero is undefined, the denominator of a fraction cannot equal zero.
To find the value of x that makes the expression undefined, set the denominator equal to zero and solve for x.
The denominator is 3 + x.
Set 3 + x equal to zero and solve for x.
3 + x = 0
Subtract 3 from both sides.
x = -3
The expression is undefined for x = -3.
