Answer:
twice
Step-by-step explanation:
y = - 1 is a horizontal line parallel to the x- axis and passing through all points with a y- coordinate of - 1
Drawing this line on the graph, from (0, - 1 ) we can see that it will intersect the graph at 2 places between (0, 0 ) and (2, - 2 ) and between (2, - 2 ) and (4, 0 )
