Answer:
the directrix and focus the axis of symmetry (goes through the focus, at right angles to the directrix) the vertex (where the parabola makes its sharpest turn) is halfway between the focus and directrix.

Step-by-step explanation:
Given
-
[ -
c + 6c + 1 ] - 3c
Distribute the square bracket by - 
=
c - 3c -
- 3c ← combine like terms
=
c - 6c - 
=
c -
c - 
= -
c - 
-(x+2)^2(x-4)^2
Not that if x= -2 and x=4 they will look like this in an equation: (x+2) and (x-4)
When (x+2) and (x-4) are set equal to zero and you solve for x, x will equal x= -2 and x=4
If they have double roots, they have a multiplicity of 2 (per root) meaning they will bounce off of the x-axis. Multiplicity can be found by using exponents.
The negative in front flips the function over the x-axis and holds true to the given limit.
30 is greater than 3. So 30 > 3
