Rumus suatu fungsi f(x) = 3x + 2. Hasil penjumlahan f( -2) dan f( 3 ) adalah
![]()
Penjelasan dengan langkah-langkah:
= f(-2) + f(3)
= 3.-2 + 2 + 3.3 + 2
= -6 + 2 + 9 + 2
= -4 + 11
= 7
maka, hasil penjumlahan f(-2) dan f(3) adalah 7
SOAL 1
___________________________________________
f(x) = 3x + 2
___________________________________________
f(-2) + f(3)
= (3(-2) + 2) + (3(3) + 2)
= (-6 + 2) + (9 + 2)
= -4 + 11
= 7
