TentukanFungsi f(x)=-4x+2 dengan g(x)=3x-7 gf)(x) b. (fg)(x) c. (gf)(5) d. (f e. (ff)(2)

langsung aja y

B.
(fog)(x) = f{g(x)}
= -4g(x) + 2
= -4(3x-7) + 2
= -12x + 28 + 2
= 30 - 12x

C.
(gof)(5) = g{f(x)}
= 3f(x) - 7
= 3(-4x +2) - 7
= -12x + 6 - 7
= -12x - 1
= -12(5) - 1
= -60 - 1
= -61

E.
(fof)(2) = f{f(x)}
= -4f(x) + 2
= -4 (-4x +2) + 2
= 16x - 8 + 2
= 16x - 6
= 16(2) - 6
= 32 - 6
= 26

semoga berguna +_+
