tolong d bntu jwb kkk
Penjelasan dengan langkah-langkah:
f(x) = px + q (bntuk umum)
eliminasi:
f(0) = 0p + q = -2
f(2) = 2p + q = 4
______________-
-2p = -6
p = -6/-2
p = 3
subs :
2p + q = 4
2(3) + q = 4
6 + q = 4
q = 4 - 6
q = -2
a.
p = 3
q = -2
b.
f(y)= 7
3y - 2 = 7
3y = 7 + 2
3y = 9
y = 9/3
y = 3
