Question

Dada a função f(x)=3x-1,calcule f(-2),f(3),f(8),f(-1)f(0),f(5).

Answer 1

Dada a função f(x)=3x-1,calcule

f(-2)= 3x-1==>3(-2)==> -6-1==> - 7
f(3)= 3x-1==>3(3)==> 9-1==> 8
f(8)= 3x-1==>3(8)==> 24-1==> 23
f(-1)= 3x-1==>3(-1)==> -3-1==> - 4
f(0)= 3x-1==>3(0)==> 0-1==> - 1
f(5)= 3x-1==>3(5)==> 15-1==> 14
