HELP PLEASE FOR 100 POINTS!! For each parabola, a) Write the equation of the function; b) Give the minimum or maximum value of the function; c) Find the domain and range.

Number 5:
a- y=x^2
b- Maximum (0,0)
c- Domain= (-infinity,+infinity)
Range=(-infinity, 0]

Number 6:
a- y=-x^2 (the - changes the direction of parabola)
b- Minimum (0,0
c- Domain= (-infinity,+infinity)
Range= [0, +infinity)

*note when I use [] and ()
same with the + and - infinities

Hope this helps! :)

1 problem is b  2 problem is c

Step-by-step explanation:

i think 88

Step-by-step explanation:

(it's been a while since I've done this so I'm not too sure it's correct)

The formula we need to use is

2πr(angle/360)

we need the radius (r)

To get r we need angle AES

180-80= 100

using the equation from before

88=2πr*(100/360)

raidus: 50.42

Then to get the length CD we need angle DEC

180-80=100

2π*50.42*(100/360)=88

there probably was some kind of shortcut we could've used to figure this out faster but whatever
