Let's draw a graph of the given function:
As we can note x can take value from minus infinity to -9 because at this point we get
[tex]\begin{gathered} f(x)=\frac{9}{10}log(-(-9+9))+10 \\ which\text{ gives } \\ f(x)=\infty \end{gathered}[/tex]
because logarithm of zero is undefined. We can also note that the graph extends from the second quadrand to the third quadrant. Therefore, the answer is option B.
