Jika F(x) = (3x - 1)2 + 2x2, hitung F(4), F(0), dan F(-4)
Jika F(x) = (3x - 1)² + 2x², hitung F(4), F(0), dan F(-4).
Jawab:
F(x) = (3x – 1)² + 2x²
F(4) = (3(4) – 1)² + 2(4)²
= (12 – 1)² + 2(16)
= 121 + 32
F(4) = 153
F(0) = (3(0) – 1)² + 2(0)²
= (0 – 1)² + 2(0)
= 1 + 0
F(0) = 1
F(-4) = (3(-4) – 1)² + 2(-4)²
= (-12 – 1)² + 2(16)
= 169 + 32
F(-4) = 201
