  1. I don't know why you wrote f(0). f(0) has nothing to do with stationary points and its value is -7. See my other answer for the x values at the stationary points, and use those two x values to calculate the corresponding y = f(x) values

  2. Well, y is the same as f(x). In other words, y = f(x) and f(x) = y because they are interchangeable.

    For example, y = x + 5 is the same as if you were to write it f(x) = x + 5.
    Did you know that?

    Do you see f(0)?

    It tells you to replace x with 0 everywhere you see the letter x and then simplify.

    Find y or f(x)when x = 0.

    f(x)= x^3 -3x^2 - 24x -7

    f(0) = (0)^3 - 3(0)^2 - 24(0) - 7

    f(0) = 0 - 0 - 0 - 7

    f(0) = -7

    The y coordinate is -7 and the entire point is (0, -7).

    Is this what you want?
