Diketahui f(x) = 3x+2. Tentukan : a. g(x) jika f°g(x) = 17-2x b. g(x) jika g°f(x) = 8-6x Tolong di bantu jawab kakak kakak

jawab

f(x)  3x+ 2

a. fog(x)= 17-2x
f{g(x)} = 17 - 2x
3. g(x) + 2 = 17 - 2x
3.g(x) = 17 - 2 - 2x
3 g(x) = 15 - 2x
g(x) = 1/3 ( 15 - 2x)


b. gof(x) = 8 - 6x
g(3x+2) = 8 - 6x
g(x) = 8 - 6 ( x -2)/3
g(x) = 8 - 2 (x - 2)
g(x)=  8 - 2x + 4
g(x) = 12 - 2x
