If you do rise over run, it would be D) 4. Domain are all the x values and range is the y values. Therefore, if you find the x value (domain) of 2 on the graph, you have to match it up with the line as you go up (rise) and you will get 4. So it means the answer choice is D) 4.
dihedral angle is the angle between two intersecting planes. So, the angle with the same measure of the dihedral angle formed by plane DAJ and plane ABC is angle JAB
