Answer:
first and last statement listed
Explanation:
because f(c) is showing time, the start of the reaction will be when the y axis = 0 (because 0 time will have passed)
we can see the value of x/c is 20 when y/f(c) is 0 (20, 0)
indicating that the concentration of the chemical is 20 milligrams/liter at the start of the reaction.
<u>{first statement correct}</u>
<em>[second statement incorrect]</em>
Because the x-value [c] is increasing with the y-value [f(c)], we know that the concentration of the chemical increases as the reaction progresses over time. (time increases, concentration increases)
<u>{last statement correct}</u>
<em>[third statement incorrect]</em>
note that "the concentration of the chemical does not fall below 20 milligrams/liter" does not say anything about when [meaning during the reaction, at the start of, or before are all being considered] the concentration is less than 20 milligrams/liter.
We can see, that <em>before</em> this reaction, the concentration of the chemical <em>does </em>fall below 20 milligrams/liter
<em>[fourth statement incorrect]</em>
