Answer:
The correct option is A. The graph will be continuous because the amount of gas that she added to the tank does not need to be an integer amount.
Step-by-step explanation:
Consider the given information.
If the value of a function is integer then the graph will be discrete, otherwise it will be a continuous graph.
The amount of gas that Jayne added does not need to be an integer. So, the graph will be continuous.
For example, 16.7 gallons of gas or 19.9 gallons of gas, etc. She can get amounts that are not integers.
This can be represent as:
<em>y</em> = <em>x</em> + 4
Where, <em>y</em> is total amount of gas in tank and <em>x</em> is number of gallons she added.
As it is a linear function which is continuous everywhere.
Thus, the correct option is A. The graph will be continuous because the amount of gas that she added to the tank does not need to be an integer amount.
