Answer:
The average rate of change is 4
Step-by-step explanation:
To find the values of y when x = 0 and when x = 2, we can graph the equation using a graphing calculator.
Looking at the graph, we can see that when x = 0 y = 5 and when x = 2 y = 13
Now that we have two points (0,5) and (2,13) we can find the rate of change
To find the rate of change we use this equation:
Let's input the values from our two points
Simplify: = 4
In the given graph, the two lines intersects at
And intersection point is that point , where the y values of the two graphs are equal .
That is
And at x=-2, the y values are equal. THat is
So the correct option is D.
