If f(x) = -2x - 9 and f(x) , then what is the value of x ?

It seems like part of your question is missing after "f(x)," but I can help based on the provided information. 

If you have \( f(x) = -2x - 9 \), and you're solving for \( x \), it depends on what value you have for \( f(x) \). For example, if you're given a specific value for \( f(x) \), say \( f(x) = 0 \), you can solve the equation for \( x \).

For instance, if:
\[
f(x) = 0 \quad \text{then} \quad -2x - 9 = 0
\]

1. Add 9 to both sides:
\[
-2x = 9
\]

2. Divide by -2:
\[
x = \frac{9}{-2} = -4.5
\]

Would you like to clarify the missing part of your question, or is this the solution you were looking for?
