Answer:
plot each coordinate pair onto the graph then solve for the function
Step-by-step explanation:
step one: plot each coordinate pain onto the coordinate graph
step two: fuse the vertical line test. Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function
