x - 2 = a
x = a + 2
g(a) = 2(a + 2) + 7
g(a) = 2a + 4 + 7
g(a) = 2a + 11
g(x) = 2x + 11
(h o g) (x) = 4x² + 44x + 1
h(g(x)) = 4x² + 44x + 1
h(2x + 11) = 4x² + 44x + 1
h(10) = ?
2x + 11 = 10
2x = 10 - 11
x = -½
h(10) = 4(-½)² + 44(-½) + 1
h(10) = 4 (¼) - 22 + 1
h(10) = 1 - 21
h(10) = -20
A
jawabannya A. kalau ada yang kurang jelas tanya aja
