Question

Tentukan nilai a jika f(x) = 3x^6 - 13x^3 + 2x^2 - 2a , jika f(2) = 88 .

Answer 1

f(x) = 3x⁶ - 13x³ + 2x² - 2a
f(2) = 88
3.2⁶ - 13.2³ + 2.2² - 2a = 88
3.64 - 13.8 + 2.4 - 2a = 88
192 - 104 + 8 - 2a = 88
96 - 2a = 88
-2a = 88 - 96
-2a = -8
a = 4

semoga membantu :)

Answer 2

F(x)=3-13+2-2a
f(2)=3-13+2-2a=88
 -->= 3(64)-13(8)+2(4)-2a=88
 -->= 192-104+8-2a=88
 -->= 96-2a=88
 -->= -2a=-8
 -->= a=4
