Question

Dada a função de lei f(x)=5x-2 calcule os valores de f(x) para: A) x=0. B) x=2. C) x=-1 D) x=1

Answer 1

A) 5.0 - 2 = -2
B) 5.2 - 2 = 8
C) 5.(-1) - 2 = -7
D) 5.1 - 2 = 3

Answer 2

f(x)=5x-2
f(0)=5.0-2
f(0)=-2

f(x)=5x-2
f(2)=5.2-2
f(2)=8

f(x)=5x-2
f(-1)=5.(-1)-2
f(-1)=-7

f(x)=5x-2
f(1)=5.1-2
f(1)=3
