Answer:
None of these answers, that I know of, remove carbon dioxide from the air, photosynthesis how ever does in fact do that.
Explanation:
Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2.
It would actually be Graph C since a proportional relationship also answers the question of determining the unit rate, slope of the line, and etc.
The unit rate is 5/1, and follows the rate into a slope making it proportional.
Hope I helped! ^-^
First off you should really type the equation in the proper order and also use the carat symbol to show that something is to the power too, so your equation shouldve looked like this.
-y^2 -4y + 4 = 0
But all yuo need to is plug the equation into a calculator and search for where it intersects the X line. the answers are
(.828, 0) , (-4.83, 0)
