Therefore, a = -2 and n = 3. From the law of exponent above, we receive:

(-2) • (-2) = 4 | Negative × Negative = Positive.

4 • (-2) = -8 | Negative Multiply Positive = Negative.
![\displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{ - 8}}](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20%5Clarge%7B%20%7B%28%20-%202%29%7D%5E%7B%20-%203%7D%20%20%3D%20%20%5Cfrac%7B1%7D%7B%20%20-%208%7D%7D)
If either denominator or numerator is in negative, it is the best to write in the middle or between numerator and denominators.
Hence,
![\displaystyle \large \boxed{ {( - 2)}^{ - 3} = - \frac{1}{ 8}}](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20%5Clarge%20%5Cboxed%7B%20%7B%28%20-%202%29%7D%5E%7B%20-%203%7D%20%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B%20%208%7D%7D)
The answer is - 1 / 8
z = 8 + 6x - px Subtract 8 from both sides
z - 8 = 6x - px Factor the x out of 6x - px
z - 8 = x (6 - p) Divide both sides by (6 - p)
![\frac{z - 8}{6 - p}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bz%20-%208%7D%7B6%20-%20p%7D%20)

Answer:
vertex: (5/6,5)
focus: (- 2/3, 5)
axis of symmetry: y = 5
directrix: x = 7/3
Step-by-step explanation:
use the vertex form to determine the values of a.h. and k and use these values to find the direction the parabola opnes, vertex, foucs, axis of symmetry, and directrix
