Diketahui
h(x) = (f o g) (x)
h(x) = x²-3x+4
a. Tentukan x jika h(x) = 8
b. Jika g(x) = x-6. Tentukan f(x)
h(x) = (f o g) (x)
h(x) = x²-3x+4
a. Tentukan x jika h(x) = 8
b. Jika g(x) = x-6. Tentukan f(x)

Jawaba) h(x) = 8
x²- 3x + 4 = 8
x² - 3x - 4 = 0
(x - 4)(x +1)= 0
x = 4 atau x = -1
b) g(x) = x- 6
fog(x) = h(x)
f (x-6) = x² -3x + 4
f(x) = ( x+6)² - 3(x + 6) + 4
f(x) = x² +12x + 36 - 3x - 18 + 4
f(x)= x² + 9x + 22
