Answer:
Height = 8 units
Step-by-step explanation:
Area of a triangle =
square units
=
square units
Height of the triangle =
units
=
units
Formula to calculate the area of a triangle is,
Area = 


Height = 
= 
= 8 units
Therefore, height of the given triangle is 8 units.
The point-slope form:

- slope
- point
We have the point
and the slope 
Substitute:

It is neither.
To be even, f(x) must equal f(-x).
If you substitute -x for x, you'd get
y = (-x)^2 - 2(-x) -8
y = x^2 +2x -8
This is not the same as the original, so this is not even.
To be odd, f(x) must equal -f(-x).
If you take the -x substitution from the last step and then multiply it by -1, you'd have:
y = -1 (x^2 +2x -8)
y = -x^2 -2x +8
This is not the same as the original either.
The function is neither even nor odd.
