In the following situation, state whether the two variables are a function and if so, identify independent and dependent variables. (see below)
explain this one. you walk through a used car lot and list the price and model year of each car you see.
a. the situation cannot be described by a function.
b. the situation can be described by a function. there is a dependent variable, but no independent variable. the dependent variable is the price.
c. the situation can be described by a function. the dependent variable is the price and the independent variable is the model.
d. the situation can be described by a function. the dependent variable is the model and the independent variable is the price.

A. The situation cannot be described by a function

Step-by-step explanation:

The price depends on the model year and another variables.

So two different cars have the same model but different prices. This means that for one year you can relate it with different prices.

If this situation could state a function it would mean that for each year there will be one price  and this isn´t happen.

We have to remember that a function is a relation that associates each element x of a set X (model year), the domain of the function, to a single element y of another set Y (price of the car), the condomain of the function.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
