Question

Se f(x)=3x+2 qual o valor da função para:a)f(-2),b)f(0),c)f(-3),d)f(1),e)f(2)

Answer 1

a) f(x)=3x+2
f(-2)= 3 (-2) +2
f(-2)= -6+2
f(-2)= -4

b) f(x)=3x+2
f(0)= 3(0)+2
f(0)=0+2
f(0) =2

c) f(x)=3x+2
f(-3)= 3(-3)+2
f(-3)= -9+2
f(-3)=-7

d) f(x)=3x+2
f(1)= 3(1)+2
f(1)= 3+2
f(1)= 5


e) f(x)=3x+2
f(2)= 3(2)+2
f(2)= 6+2
f(2)= 8
