Kak tolong jawabkan napa kak please besok di kumpul

Materi Fungsi Komposisi



No. 1
f(x) = x - 2

fog(x) = 3x + 1
f(g(x)) = 3x + 1
g(x) - 1 = 3x + 1
g(x) = 3x + 1 + 1
g(x) = 3x + 2

No. 2
f(x) = 4x - 1

fog(x) = x² + x + 1
f(g(x)) = x² + x + 1
4g(x) - 1 = x² + x + 1
4g(x) = x² + x + 2
g(x) = (x² + x + 2) / 4



No. 3
f(x) = 4x - 1

fog(x) = 2x² - x + 3
f(g(x)) = 2x² - x + 3
4g(x) - 1 = 2x² - x + 3
4g(x) = 2x² - x + 4
g(x) = (2x² - x + 4) / 4


No/ 4
g(x) = x + 1

fog(x) = 2x - 4
f(g(x)) = 2x - 4
f(x + 1) = 2x - 4
f(x) = 2(x - 1) - 4
f(x) = 2x - 2 - 4
f(x) = 2x - 6

No. 5
g(x) = x + 3

fog(x) = x² + 4
f(g(x)) = x² + 4
f(x + 3) = x² + 4
f(x) = (x - 3)² + 4
f(x) = x² - 6x + 9 + 4
f(x) = x² - 6x + 13
