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.
Parabola equation with a vertex at (h, k) is given by y = a(x - h)^2 + k
For the give parabola, y = a(x - 4)^2 - 3
y = a(x^2 - 8x + 16) - 3
At (5, -6)
-6 = a((5)^2 - 8(5) + 16) - 3 = a(25 - 40 + 16) - 3 = a - 3
a = -6 + 3 = -3
Therefore, the coefficient of the squared expression is -3.
