1/x is smallest when x is the largest it can be, so it is 1/3
1/y is smallest when y is the largest it can be, so it is 1/5
The average of 1/3 is 1/5 can be found by adding them together and dividing by 2:
1/3 + 1/5 = 5/15 + 3/15 = 8/15
Divide it by 2:
4/15
The answer is C.
The vertex would be (5,-23)
I think the answer you’re looking for is
Point Y

The coefficient for the equation is -24, because the formula applies like this
f(x) = (x^3 + 3x^2 + 3)(3x^3 - 6x^2 - 8x + 1)
= +(x^3) (-8x) + (2x) (3x^3)
Once we simplified through it all, we should be the answer
f"(x) = -24x^2
