Approximately 1.143 L of peroxide should be added to the original solution.
After consideration I'm not sure but I think x=3 and y=6 I'm not a math whiz but this made sense to me.
Number 1 is A, number 2 is B number three is D
The function with the smallest rate of change is B.
Rate of change is like slope, the vertical change over the horizontal change.
The horizontal change for each of these choices will be ONE since 3-2 = 1.
Plug 2 in for x to find y, then plug 3 in for x and find y. Subtract the y values and you will get the rate of change as follows:
A) 30
B) 7
C) 192
D) 12
If you need more explaining just let me know.
