Diketahui polinom f(x) = 4x2 – 9 g(x) = x4 – 3x2 + 1 Tentukan h(-3), jika h(x) = 3f(x) – 2g(x)!
Diketahui polinom
f(x) = 4x2 – 9
g(x) = x4 – 3x2 + 1
Tentukan h(-3), jika h(x) = 3f(x) – 2g(x)!
Jawab:
h(x) = 3f(x) – 2g(x)
= 3(4x2 – 9) – 2(x4 – 3x2 + 1)
= 12x2 – 27 – 2x4 + 6x2 – 2
h(x) = -2x4 + 18x2 – 29
h(-3) = -2(-3)4 + 18(-3)2 – 29
= -162 + 162 – 29
h(-3) = -29
