  • f(x) = x² + 6

    f(x+2) = (x+2)² + 6
    f(x+2) = x² + 4x + 4 + 6
    f(x+2) = x² + 4x + 10

    semoga membantu 
  • f(x) = x^2 + 6
    f(x + 2) ?
    -->
    f(x + 2)
    = (x + 2)^2 + 6

    (X + 2)^2
    = (x + 2)(x+2)
    = x^2 + 2x + 2x + 4
    = x^2 + 4x + 4

    -->
    x^2 + 4x + 4 + 6
    f(x + 2)= x^2 + 4x + 10
