suatu pemetaan dirumuskan dengan g(x) = px + 5. jika g(3) = -1, maka g(p)

g(x) = px + 5                => g(3) = -1
          p(3) + 5 = -1
                   3p = -1 - 5
                   3p = -6
                     p = -6/3
                     p = -2

g(p) = ?
g(-2) = px + 5
         = -2(3) + 5
         = -6 + 5
         = -1

maaf kalo salah, smoga membantu ^-^
