Question

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.

Answer 1

1 problem is b 2 problem is c

Explanation:

Answer 2

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! :)
