5!! =

5 × 3

= 15

f(x) = 3x² + 4x²

f(15) = 3(15)² + 4(15)²

f(15) = 3(225) + 4(225)

f(15) = 675 + 900

f(15) = 1.575

Jawaban:

F(x) = 3x² + 4x²

F(15) = 3(15)² + 4(15)²

F(15) = 3(15 × 15 ) + 4(15 × 15 )

F(15) = ( 3 × 225 ) + ( 4 × 225 )

F(15) = 675 + 900

F(15) = 1.575

5!!

= 5 × 3 × 1

= 15 × 1

= 15
