Expert Solution
Step 1

Solution ) f (x) = x - 8 , g (x) = 7x + 9

a ) ( f + g )x = f(x) + g (x) 

( f + g )x  =  x - 8 + 7x + 9 

( f + g )x  = 8x + 1

b ) ( f - g )x = f (x) - g (x) 

( f - g )x = x - 8 - ( 7x + 9)

( f - g )x = x - 8 - 7x - 9

( f - g )x = - 6x - 17

c) ( f *g)x = f (x) × g(x)

( f *g)x = ( x - 8 ) ( 7x + 9 )

( f *g)x = 7x2 + 9x - 56x - 72

( f *g)x = 7x2 - 47x - 72
