Jawab

kurva  melalui (0,0) dan puncak (2,4)
y = a(x- 2)² + 4
0  = a (0-2)²  + 4
4a  = - 4
a = - 1
pers kurva  y  = -(x-2)² + 4
y = - x² + 4x  - 4 + 4
y = - x² + 4x

pers garis melalui  (0,0)  dan(3,3) → y = x

batas integral  x = 0  , x =  3

Luas = ₀³∫  (-x² + 4x) - (x ) dx
Luas =  - 1/3 x³  + 3/2 x² ] ³₀
Luas = - 1/3 (27) + 3/2 (9)
Luas = - 9 + 27/2 = 9/2

Answer 2

A 9/2 maaf kalo salah
