Answer 1

✧Diketahui:

x = 3

________________________________________________

✧Jawaban:

f(x) = 7x + 5x - x²

f(3) = 7(3) + 5(3) - 3²

f(3) = (7 × 3) + (5 × 3) - (3 × 3)

f(3) = (7 + 7 + 7) + (5 + 5 + 5) - (3 + 3 + 3)

f(3) = (14 + 7) + (10 + 5) - (6 + 3)

f(3) = 21 + 15 - 9

f(3) = 26 - 9

f(3) = 17

Answer 2

Jawaban:

Diket:

X = 3

Di jawaban:

F(x) = 7x + 5x - x²

F(3) = 7(3) + 5(3) - 3²

F(3) = ( 7 × 3 ) + ( 5 × 3 ) - ( 3 × 3 )

F(3) = ( 7 + 7 + 7 ) + ( 5 + 5 + 5 ) - ( 3+3 + 3 )

F(3) = ( 14 + 7 ) + ( 10 + 5 ) - ( 6 + 3 )

F(3) = 21 + 15 - 9

F(3) = 26 - 9

F(3) = 17
