Step 4: Is the function increasing or decreasing? Why?
-It is increasing because the graph line points down and right and has a positive slope.
-It is decreasing because the graph line points down and right and has a negative slope.
-It is decreasing because the graph line points up and right and has a negative slope.
-The function is neither increasing nor decreasing.
-It is increasing because the graph line points up and right and has a positive slope.
