2x-5 if x < -5f(x)= x² + 5x if -5 < x < 5x³ + 10 if x ≥ 5

ANSWER:
-6
EXPLANATION:
Given:
To find f(-3), we'll use the second function since -3 lies between -5 and 5;
[tex]\begin{gathered} f(x)=x^2+5x \\ \\ f(-3)=(-3)^2+5(-3) \\ \\ f(-3)=9-15 \\ \\ f(-3)=-6 \end{gathered}[/tex]Therefore, f(-3) = -6
