f(x) = 2x + 2
--
f(1) = 2(1) + 2
f(1) = ( 2 × 1 ) + 2
f(1) = 2 + 2
f(1) = 4
--
f(2) = 2(2) + 2
f(2) = ( 2 × 2 ) + 2
f(2) = 4 + 2
f(2) = 6
--
f(3) = 2(3) + 2
f(3) = ( 2 × 3 ) + 2
f(3) = 6 + 2
f(3) = 8
Jawaban:
f(x) = 2x + 2
f(1) = ...?
= 2 ( 1 ) + 2
= ( 2 × 1 ) + 2
= 2 + 2
= 4
f(2) = ...?
= 2 ( 2 ) + 2
= ( 2 × 2 ) + 2
= 4 + 2
= 6
f(3) = ...?
= 2 ( 3 ) + 2
= ( 2 × 3 ) + 2
= 6 + 2
= 8
