I think the answer is 300+20+8
and 400+7 :)
Best way I would say is to graph both lines and see if they are parallel to eachother
The 0's keep adding up and up and up is q
Since f(-2) means that our x-value is -2, we can go to that position on the graph and slide up the y-axis to find the intersection this point has with the function graphed.
If I am correct the answer should be that the y value is 2!
