2. The graphs below show functions for . Match the functions below with the graphs? and explain what you used to make each match. Note the graphs are not all at the same scale: look closely at the vertical tick marks. \[ \begin{array}{II} f(x)=\sin x & g(x)=\cos x \\ h(x)=3 \sin x & i(x)=-4 \cos x \\ j(x)=\sin (x)+3 & k(x)=\cos (x)-4 \\ I(x)=2 \sin (x)+1 & m(x)=-3 \cos (x)-1 \end{array} \]
