    for x = -1, we use the second row since -1 is between -3 and 6 for x = 3, we use the second row since 3 is between =3 and 6

    first step is to find f(x) when x = -1 since -1 is between -3 and 6, we look at the second row of the function second step is to find f(x) when x = 3 since 3 is between -3 and 6, we look at the second row of the function

    Would that answer be -2?

    no, please try again what is f(x) when x = -1?

    right! since -1 is between -3 and 6, we use the second row of the function to find our answer now, can you tell me what f(3) = ?

    if x = 3, then f(x) = ?

    not quite, since x = 3, we use the second row again, since 3 is between -3 and 6
