Kak tolong jawab no 26 pake rumus haei in d kumpul plisss

f(x) = 5x^2 +14x -3
Subtitusi
f(-2) = 5.-2^2 + 14.-2 -3
f(-2) =5.4 -28-3
f(-2) = 20-28-3
f(-2) = -11 D

f(x) = 5x^2 + 14x - 3
f(-2) = 5(-2)^2 + 14(-2) - 3
f(-2) = 5(4) + 14(-2) - 3
f(-2) = 20 - 28 - 3
f(-2) = -11

jangan lupa bintang 5 ya ..hehe
