Algebra 2 , 69 points (nice) and brainiest if possible!
describe a relationship that can be modeled by the function represented by the graph, and explain how the function models the relationship.
then, identify and interpret the key features of the function in the context of the situation you described.

This is a fairly straightforward piecewise function. The functions can be determined if you give me the vertex and one additional point of the dip in the graph. I also need 2 points in the green line. I can help you better if you provide me with these details because the pic is not very clear. Hope this helped a little.

Step-by-step explanation:

1) Use the vertex formula y=a(x-h)+k where h and k is the vertex and solve for a with additional point you can plug in.

2) find the green line by using the y=mx+b formula

3) Use the y= some number formula for blue line.

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
