We are given that
points through which parabola is passing
(-1,1) and (1,-3)
so, we have
x1=-1 ,y1=1
x2=1 , y2=-3
we can find average rate of change by using formula
now, we can plug values
So, the average rate of change from -1 to 1 is -2...........Answer
Hey there!
(-2/5)^2
= (-2/5)(-2/5)
= -2(-2) / 5(5)
= 4/25
Therefore, your answer is l: 4/25
Good luck on your assignment and enjoy your day!

Answer:
Part 1.
Juice = 8 L.
Lemonade = 32 L.
Part 2.
20 L punch Josie can make.
Part 3.
New ratio juice : lemonade = 2 : 9
Step-by-step explanation:
Part 1.
1+4 = 5 parts altogether, 1 parts for juice and 4 parts for lemonade.
40 : 5 = 8 L is 1 part.
Juice - 1 part - 8 L.
Lemonade - 4 parts - 4*8 = 32 L.
Part 2.
1 parts of juice needs 4 parts of lemonade
4 L of juice needs x L of lemonade
1 : 4 = 4 : x
x = 4*4/1 = 16 L lemonade
4+ 16 = 20 L punch Josie can make
Part 3.
It was 4 L of juice and 16 L of lemonade.
After 2 L lemonade was added, we have 4 L of juice and (16+2) = 18 L of lemonade.
4 L juice : 18 L lemonade = 4/2 L juice : 18/2 L lemonade =
= 2 L juice: 9L lemonade
New ratio juice : lemonade = 2 : 9
