Q.

The graph shows the volume $\mathrm{V}$ (in cubic feet) of a cube with an edge length of $\mathrm{x}$ feet. Does graph represent a linear or nonlinear function?

Q. 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.

1. $x$ and $y$ are non-negative integers.
2. $x$ and $y$ are non-negative integers.
3. $x$ and $y$ are non-negative integers.

Q. To represent a function graphically, we find ordered pairs that satisfy function rule, plot them, and then connect them in a smooth curve.

1. True
2. False

Q.
