Answer

\( h(6)=57 \)

Steps

Step 1 :\( h(x)=2 f(x-2)-3 g(x-3) \)

Step 2 :\( h(6)=2 f(6-2)-3 g(6-3) \)

Step 3 :\( h(6)=2 f(4)-3 g(3) \)

Step 4 :\( f(x)=x+2 \)

Step 5 :\( f(4)=4+2 \)

Step 6 :\( f(4)=6 \)

Step 7 :\( g(x)=-5 x \)

Step 8 :\( g(3)=-5(3) \)

Step 9 :\( g(3)=-15 \)

Step 10 :\( h(6)=2(6)-3(-15) \)

Step 11 :\( h(6)=12+45 \)

Step 12 :\( h(6)=57 \)
