Jawab
fungsi

1, g(x)= 2x²+ 4x + 2
x = -b/2a 
x = - 4/ (2. 2)
x = - 4/4
x = -1
g(-1) = 0
tikbalik min (-1,0)

2. y = x² -1
x= 0 , y = -1
tik pot dgn sb y di (0, -1)

3. y = 5x² - 2x + 10
a= 5, b =- 2 , c = 10
a + b + c = 5 - 2 + 10  = 13

4. y = ax² + bx + c
tik pot dgtn sb y, x = 0 , y = c
titk (0, c)

5. y = x² + 3px + 6
a= 1 , b = 3p , c = 6
x= -b/2a
3 = - 3p/2
-3p = 6
p = 6/-3 
p = -2

6. y = 2x² - 7x + 6
titik pot denga sb y , x = 0 , y = 6
titk (0, 6)

7. y = - 1/3x² - 1/3 x + 2
tikpot dengan sb x , y = 0
-1/3 x² - 1/3 x + 2 = 0 ---> kalikan -3
x² + x - 6 = 0
(x + 3)(x - 2)=0
x = - 3 atau x = 2
titk pot (-3,0) atau (2, 0)
