Question

Kak jawab ini dong
besok saya mau ulangan
please

Answer 1

Verified answer

F(x) = x - ½ x²

1. Grafik memotong sumbu x , jika y = 0
x - ½ x² = 0
x(1 - ½ x ) = 0

x = 0 atau x = 2

(0 , 0) dan (2 , 0)

2. Grafik memotong sumbu y , jika x = 0
0 - ½ (0)² = 0

(0 , 0)

3. Titik Simetris
x = -b/2a
=>- 1 / 2(- ½)
=> 1

D = b² - 4ac
= 1² - 4(-½)(0)
= 1

Puncak =>(1 , 1)

Domain : {x | -2 ≤ x ≤ 4 , x ∈ R}
