Siapa cepat dia dapat^^

​

Answer 1

f(2) = 6x + 4

f(2) = 6(2) + 4

f(2) = (6 × 2) + 4

f(2) = 12 + 4

f(2) = 16

g(2) = 2x - 3

g(2) = 2(2) - 3

g(2) = (2 × 2) - 3

g(2) = 4 - 3

g(2) = 1

f(x) + g(x)

16 + 1

= 17

koreksi

Answer 2

Jawaban:

f(2) + g(2) = 17

Penjelasan dengan langkah-langkah:

f(x) = 6x + 4

g(x) = 2x - 3

cara 1 :

f(2) + g(2)

= ( 6(2) + 4 ) + ( 2(2) - 3 )

= ( 12 + 4 ) + ( 4 - 3 )

= 16 + 1

= 17

cara 2 :

f (x) = 6x + 4

f (2) = 6(2) + 4

f (2) = 12 + 4

f (2) = 16

..

g (x) = 2x - 3

g (2) = 2(2) - 3

g (2) = 4 - 3

g (2) = 1

...

f(2) + g(2)

= 16 + 1

= 17

cara 3 :

f(2) + g(2) --> f(x) + g(x)

= 6x + 4 + 2x - 3

= (6+2)x + 4 - 3

= 8x + 1 --> 8(2) + 1

= 16 + 1

= 17
