Diketahui fungsi f(x)=4-2x , g(x)=3x-1,dan h(x)= 5x + 2 , maka ( f ° g ° h) (-1) adalah.. a.22 b.23 c.24 d.25 e.26

komposisi

(fogoh) = 
cari goh terlebih dahulu

goh (x) = g (5x+2) = 3(5x+2)-1 = 15x+6-1 = 15x+5

cari fogoh = f (15x+5) = 4- 2 (15x+5) = 4-30x-10 = -30x-6 = -30 (-1)-6 = 30-6 =24

jadi jawaban c
