we will compensation (-5) for each x at g(x) it will be (-4(-5))+3= 23 then put 23 for each x at f(x) and it will be (-2(23))-7=-53

put (-7) for each x at g(x) $\frac{ (-7)+8 }{ (-7) }$=$\frac{ -1 }{ 7 }$ then put (-1\7) for each x at f(x) it will be $(\frac{ -1 }{ 7 })^{2}+6$=$\frac{ 295 }{ 49 } or 6.020$
