c. f(x) + f(x) - f(1)
f(1)= 2
f(2)=1
Jadi f(1)= a + b=2}
f(2)= 2a +b = 1} nah ini semua pakai eliminasi. Jadi - a = 1 ➡️ a= - 1, selanjutnya kita mencari b yaitu 2a+b =1 ➡️ 2.-1 + b = 1 ➡️ b= 2+ 1
b= 3.
f (x-1) = - 1 (x-1) + 3 = 1
= - x +1 +3= 1
= - x = 1-4
= - x = - 3
= x= 3
.
f(x) + f(x-1) =.... (-1.3 + 3) + (-1.2 + 3) =1
Jadi c. Bentuk paling sederhana yaitu = 1
b. ➖➖➖➖➖➖➖➖➖➖➖ x diketahui 3.
