NOTE: Value range for testing is 0 <= x <= 12.

HINT: You can use Python to calculate correct results of f(x) to be used for checking.

1. Function f(x) that handles cases:

    f(x) = -7 * x - 6 if x < 3
    f(x) = 3 if x >= 3
    f(x) = 5 * x**7 + 5 * x**6 - 9 * x if x == 8
    f(x) = -4**x + 3 if x > 10
