Question

F(x)=4x-7
Nilai f(3+1) + f(2) = …

Answer 1

F(x) = 4x-7
f(3+1)+f(2) =
f(3+1) = 4(3+1)-7
= 4.4-7
= 9
f(2) = 4(2)-7
= 8-7
= 1
f(3+1)+f(2)= 9 + 1 = 10

Answer 2

F(3+1) = 4(3+1)-7
          = 12+1-7
          = 6
f(2)     = 4(2)-7
          = 8 -7
          = 1
Jadi f(3+1)+ F(2) = 6+1 = 7

maaf kalo salah
