find f(-15) + 4g(-9) in simplified form.

Explanation:

Step1: Find the value of $f(-15)$

From the table, when $x = - 15$, $f(-15)=-9$.

Step2: Find the value of $g(-9)$

From the table, when $x=-9$, $g(-9) = 11$.

Step3: Calculate $4g(-9)$

$4g(-9)=4\times11 = 44$.

Step4: Calculate $f(-15)+4g(-9)$

$f(-15)+4g(-9)=-9 + 44=35$.
