Step-by-step Solution
To solve the problem, we need to evaluate the function \( F(x) \) at \( x = -1 \). The function \( F(x) \) is defined piecewise, which means it has different formulas for different intervals of \( x \).
The function is defined as follows:
\[ F(x) = \begin{cases}
2x + 1 & \text{if } -1 > x \\
-2 & \text{if } x \geq -1
\end{cases} \]
We need to determine which formula to use for \( x = -1 \). Since \( x = -1 \) is equal to -1, it falls into the second interval where \( x \geq -1 \).
Therefore, we use the second formula:
\[ F(x) = -2 \]
Now, we substitute \( x = -1 \) into this formula:
\[ F(-1) = -2 \]
So, the value of the function \( F(x) \) at \( x = -1 \) is \( -2 \).
Quick Answer
The value of \( F(-1) \) is \( -2 \).
