5. Let f be the function whose graph is shown above; the graph of f consists of three line segments.
Let g be a differentiable function. The table above gives values of g and its derivative g′ at various values of x.
Let q be the function defined as q(x)=f(−3x)⋅g(−2x). Find q′(−1).
q′(x)=−3⋅f′(−3x)⋅g(−2x)+f(−3x)⋅(−2)⋅g′(−2x)
q′(−1)=−3⋅f′(3)⋅g(2)+f(3)⋅(−2)⋅g′(2)=(−3)(2)(3)
