f (x) = 6x-5 , g(x) = 5-10x tentukan a (fog) (x) b (gof) (x) c (fog) (1) d (sof) (2)

a.
[tex]5 - 10(6x - 5) \\ = 30x - 60x - 25 + 50 \\ = - 30x + 25[/tex]
b.
[tex]6x - 5(5 - 10) \\ = 30x - 25 - 60x + 50 \\ = - 30x + 25[/tex]
c
[tex]5 - 10((6 \times 1) - 5) \\ = 30x - 60x - 25 + 50 \\ = - 30x + 25[/tex]
kyaknya sih.. maaf klo salah gw kan sotoy
