Jawab:

komposisi fungsi

a, g(x) =  3x+ 2
fog(x) =  9x² +15x - 7

f{g(x)} = 9x² +15x - 7
f(3x+2) = (3x+2)² + (3x + 2) + 1
f(x) =  x² + x + 1

b. f(x) = 3x + 2
fog(x) = 9x² +15 x -7
3. g(x) + 2 = 9x² +15x - 7
3. g(x) = 9x² +15x - 7 -2
3. g(x) = 9x² +15x - 9
g(x) = 1/3 (9x² +15x - 9)
g(x) =  3x² + 5x - 3
