I think when you subtract 4 from x, you are shifting the graph right horizontally 4 units. When you add 84 at the end of the function, you are shifting it up vertically 84 units. When you times it by -5, you are stretching it by a factor of 5 and flipping it upside down.
just think of how each term effects the y value.

Answer:
Yes, it is 368.24, because you cannot use a digit more than once.
Step-by-step explanation:
The answer is letter c. x2-8x+24-[72/(x+3)]. If you do not know how to solve this using the long division method, you can always evaluate the options through the process of elimination first. Since the degree of the other factor is already 1 (x to the power of 1), you know that option d. is not the correct answer because you know that the other factor must be raised to the power of 2. That leaves us with a, b and c. Working backwards and multiplying the given factor (x+3) with the factor in b, gives us x3-5x2+72. So from there, you know that you have to eliminate 72, which can be removed when it is subtracted by itself. Letter c does just that. Try multiplying (x+3) and option c for yourself :).
