If f(x) = 3x +2, find each value f(4) f(8) f(-2)

f(x) = 3x + 2

f(4) = 3(4) + 2   = 12 + 2   = 14

f(8) = 3(8) + 2   = 24 + 2   = 26

f(-2) = 3(-2) + 2   = -6 + 2   = -4

f(4)=14, f(8)=26, f(-2)=-4

f(4) = 3(4)+2

     = 12+2

     = 14

f(8) = 3(8)+2

     = 24+2

     =26

f(-2) = 3(-2)+2

       = -6+2

       = -4

I hope this helps
