Matematika

Nomor 34

f'(x) = 5x`³

f(x) = 5/(-3+1) x^(-3+1)

= (- 5/2) x`²

= - 5/2x²

Nomor 35

f"(x) = 6x + 8

f'(x) = 3x² + 8x

f'(1) = 3(1)² + + 8(1)

= 3 + 8

= 11

karna f'(1) = 5 maka

f'(x) = 3x² + 8x - 6

f(x) = 3/(2+1) x³ + 8/(1+1)x² - 6x

f(x) = x³ + 4x² - 6x

f(2) = (2)³ + 4(2)² - 6(2)

= 8 + 16 - 12

= 8 + 4

= 12

karna f(2) = 15 maka

f(x) = x³ + 4x² - 6x + 3
