For what value of x is the expression \(\frac{2x - 1}{x + 3}\) not defined?
Answer Details
The expression \(\frac{2x-1}{x+3}\) is undefined if the denominator is equal to zero, since division by zero is not allowed in mathematics. Therefore, we need to solve the equation \(x+3=0\) to find the value of x for which the expression is undefined.
Solving for x, we have:
\begin{align*}
x+3 &= 0 \\
x &= -3
\end{align*}
Therefore, the expression is not defined for x = -3. Thus, the correct answer is (-3).
