f(x) = 2x + 4

maka:

f(2) + f(1) = ...
​

Answer 1

Penjelasan dengan langkah-langkah:

f(x) = 2x + 4

______________________

f(x) = 2x + 4

f(2) = 2x + 4

f(2) = 2(2) + 4

f(2) = (2.2) + 4

f(2) = 4 + 4

f(2) = 8

______________________

f(x) = 2x + 4

f(1) = 2(1) + 4

f(1) = (2.1) + 4

f(1) = 2 + 4

f(1) = 6

______________________

= f(2) + f(1)

= 8 + 6

= 14
