To solve the equation \( 9x - 6 = -8 \), we can rearrange it into the form of a function.
First, add 6 to both sides of the equation:
\[ 9x = -8 + 6 \] \[ 9x = -2 \]
Next, divide both sides by 9:
\[ x = -\frac{2}{9} \]
To express the original equation as a function, we can set \( f(x) = 9x - 6 \) and find where this equals -8:
\[ f(x) = 9x - 6 \]
This tells us that to solve the equation \( 9x - 6 = -8 \), we need to graph \( f(x) = 9x - 14 \) (since \( 9x - 6 + 8 = 0 \) leads to \( 9x - 14 = 0 \)).
Based on the options given, the correct function to graph is:
f(x) = 9x - 14.
