Answer 2

Jawaban:

Diketahui:

• Lim ( 5x + 7x - 5² )

Ditanya:

• x → 5 + x → 4 - x → 3

Jawab:

• x → 5

Lim ( 5x + 7x - 5² )

Lim ( 5(5) + 7(5) - 5² )

Lim ( ( 5 × 5 ) + 7(5) - 5² )

Lim ( 25 + 7(5) - 5² )

Lim ( 25 + ( 7 × 5 ) - 5² )

Lim ( 25 + 35 - 5² )

Lim ( 25 + 35 - ( 5 × 5 ))

Lim ( 25 + 35 - 25 )

Lim ( 60 - 25 )

Lim = 35

• x → 4

Lim ( 5(4) + 7(4) - 5² )

Lim ( ( 5 × 4 ) + 7(4) - 5² )

Lim ( 20 + 7(4) - 5² )

Lim ( 20 + ( 7 × 4 ) - 5² )

Lim ( 20 + 28 - 5² )

Lim ( 20 + 28 - ( 5 × 5 ) )

Lim ( 20 + 28 - 25 )

Lim ( 48 - 25 )

Lim = 23

• x → 3

Lim ( 5x + 7x - 5² )

Lim ( 5(3) + 7(3) - 5² )

Lim ( ( 5 × 3 ) + 7(3) - 5² )

Lim ( 15 + 7(3) - 5² )

Lim ( 15 + ( 7 × 3 ) - 5² )

Lim ( 15 + 21 - 5² )

Lim ( 15 + 21 - ( 5 × 5 ) )

Lim ( 15 + 21 - 25 )

Lim ( 36 - 25 )

Lim = 11

• maka :

x → 5 + x → 4 - x → 3

= 35 + 23 - 11

= 58 - 11
