Ryan is studying the effects of an organic plant food on the growth
of a sprouting bean plant for his
science fair project.
Over the course of 6 days, he
added a total of 72 milliliters of
the plant food to his soil. He also
measured the height of his bean
sprout each day.
what does the x-intercept of this relationship represent 1.the length of time it takes for the height of the plant to reach 72 centimeters 2.the amount of plant food used each day 3. The length of time it takes for Ryan to use all the plant food 4. The initial amount of plant food

The correct option is;

4. The initial amount of plant food

Step-by-step explanation:

The x-intercept is the point and the value of the variable, x at which the function measured f(x) is 0

From the information given, the quantities measured are the quantity of plant food added and height of the bean sprout

Given the nature of the observational experiment, we have that, the variable x which can determined by the researcher is the quantity of the added plant food while the function of the variable y = f(x) is the height of the bean sprout.

Therefore, y = 0 which is the x-intercept, represents the start of the experiment (consisting of natural numbers) which gives the initial amount of plant food added to the soil.

idk lol xd
