Use a mapping diagram to determine whether the relation is a function. (3, 6), (5, 7), (7, 7), (8, 9)

Part a: select all of the ordered pairs that are located on the graph of the equation. part b: does the graph of the equation represent a function? select all correct answers for part a and one answer for part b.

Add the two expressions 3.8b - 7 and 2.9b + 9 enter your answer in simplified form
