Question

Gabriel has offered some chocolates to his little brother on his birthday. Each chocolate generates two wrappers. Construct a function that can represent the number of chocolates versus the number of wrappers generated and plot it on a graph.

• A. $x$ and $y$ are non-negative integers.
• B. $x$ and $y$ are non-negative integers.
• C. $x$ and $y$ are non-negative integers.

Answer 1

The correct option is C $x$ and $y$ are non-negative integers.

Each chocolate generates two wrappers.
$\therefore$ The number of wrappers will be generated twice the number of chocolate consumed.

Here, the number of chocolate consumed is an independent variable $x$, and the number of wrappers generated $\left(y\right)$ is dependent on the number of chocolate consumed.
$\Rightarrow y=2x$
Let's form the ordered pairs. x y

1	2	3
2	4	6

But plotting these points on the coordinate plane and joining them, we get the required graph.
Here, $x$ and $y$ are non-negative integers.
