Persamaan
(3x+1)(3x+1) = 9x²+6x+1
Titk potong sb x = (-1/3,0)(-1/3,0)
titik potong sb y = (0,1)
titip puncak = -D/4a
-b²-4ac/4a
-36-36/36
-72/36
-2 (titik puncak)

semoga membantu:)

persamaan
(3x+1)(3x+1) = 9x²+6x+1

Titk potong sb X = (-1/3,0)(-1/3,0)

Titik potong sb Y = (0,1)

Titip puncak = -D/4a
= -b²-4ac/4a
= -36-36/36
= -72/36
= -2
