Answer 1

Explicação passo-a-passo:

A) f(0)-f(3)

(3.0 + 15) - (3.3 + 15)

(0 + 15) - (9 + 15)

(15) - (24)

- 9

B) f(5)-f(10)

(3.5 + 15) - (3.10 + 15)

(15 + 15) - (30 + 15)

(30) - (45)

- 15

C) f(7)-f(3)

(3.7 + 15) - (3.3 + 15)

(21 + 15) - (9 + 15)

(36) - (24)

12

D) f(5)-f(2)

(3.5 + 15) - (3.2 + 15)

(15 + 15) - ( 6 + 15)
