Question

Dada a função f, com f(x)=3x -1 ,determine no caderno:
a) f(1) - f(0)
b) f(2) - f(1)
c) f(3) - f(2)
d) f(4) - f(3)

Answer 1

F(x) = 3x -1

A) F(1) - F(0) = (3.1 -1 = 2) - (3.0 -1 = -1) = -1
B) F(2) - F(1) = (3.2 -1 = 5) - (3.1 -1 =  2) = 3
C) F(3) - F(2) = (3.3 -1 = 8) - (3.2 -1 =  5) = 3
D) F(4) - F(3) = (3.4 -1 = 13) - (3.3 -1 = 8) = 5
