The path a character takes to navigate a level of a video game is given in the following graph. Piecewise function with a linear function going from a closed point at negative 12 comma negative 6 to an open point at negative 6 comma negative 6 and another linear function from a closed point at negative 6 comma negative 4 up to the point 2 comma 4 and then horizontally to a closed point at 8 comma 4 and then another linear function from an open point at 8 comma 0 down to a closed point at 14 comma negative 3

What is the domain?

The domain is the set of x values that has a corresponding y-values in a function or a graph.

The domain of the graph is:

From the graph (see attachment), we have the following observation

These values can be represented as:

So, the domain of x is:

for the points! : )

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
