Answer 1

a. f(x) = 4x² - 12x + 9

( - b/2a, - d/4a)

x = - (12)/2 (4) = 12/8

= 3/2

d = b²n - 4ac

- (12 )² - 4 (4 ) ( 9)

= 144 - 144 = 0

y = - d/4a

= - 0 / 4/(4)

= 0

koordinat titik balik fungsi (x,y) = ( 3/2,0) ✔

b. xp = - b/2a

= - ( - 12) /2( 4 )

= 12/8

= 3/2

Jadi sumbu simetrinya adalah x 3/2✔

c. Nilai minimum :

- d/4a = - b² - 4ac/4a

= - ( - 12)² - 4( 4 ) ( 9 )/ 4/( 4 )

= - 144 - 144/ 16

= - 0/16

= 0 ✔
