use the graph below to answer this question: find the average rate of change for the given function from x=1 to x=2.

Answer: D. 2

Step-by-step explanation:

The question is asking for the rate of change from x=1 to x=2. Remember that the rate of change is also the slope, which can be seen as $\frac{rise}{run} or \frac{y}{x}$ . The rise would be going up/down the graph and the run would go left/right of the graph. Let's look at where x=1 and x=2 on the graph.

First, look at where the line falls between x=1 and x=2. Then, on where x=1, go up, then right on the graph, until you find the point where x=2. In this case, <u>the rise over run is </u> $\frac{2}{1}$ <u>. This can be simplified to 2</u>.
