Question

Tolongg dibuat sama caranyaa yaa .. pliss bangett .. bsk mau kumpull soalnyaaa
soalnyaa yg dilingkar yaa

Answer 1

37)
y = - (x-3)(x+3)
y = - (x²- 9)
y = 9 - x²

38) pers sumbu simetris = x = (3 -1)/2 = 1

39) pda gam,bar garik memotong x di  x= -3 dan x = 5

40) P(1,4) melalui (-1,0) atau (3,0)
y = a (x+1)(x-3)
4 = a(1+1)(1-3)
4 = a(-4)
a = -1
y = -(x+1)(x-3)
y = -x² + 2x + 3

48)
pers sumbu simetris = x = (-12 + 2) /2 =-5
x= -5 ---> y = (-5)² +10(-5) - 24 = - 49
(-5, -49)
