Bab Fungsi
Matematika SMA Kelas XI

a] (f - g) (x) = (2x² - 3x + 1) - (x² + x - 2) = x² - 4x + 3

b] (f / g) (x)
= (2x² - 3x + 1) / (x² + x - 2)
= ((2x - 1) (x - 1)) / ((x + 2) (x - 1))
= (2x - 1) / (x + 2)

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

a. (f-g) (x)
= f(x) - g(x)
= 2x^2 - 3x + 1 - x^2 + x - 2
= x^2 - 2x - 1.

b. (f/g) (x)
= f(x) / g(x)
= 2x^2 - 3x + 1 / x^2 + x - 2
= (2x-1)(x-1) / (x+2)(x-1)
= 2x-1 / x+2

Semoga membantu;)
