1 answer:
Graphs are used to represent functions.
Sara's mistakes are:
- Graph A: The intervals on the y-axis are not uniform
- Graph B: The origin of the graph is wrongly placed.
<u>Graph A</u>
When a graph is plotted, the intervals on both axes must be uniform.
In Sara's graph, the intervals on the y-axis do not follow a uniform pattern (i.e. 0, 1, 2, 4, 8)
Instead, she could have used 0, 2, 4, 6, 8.....
<u>Graph B</u>
The origin of a graph is always 0
In Sara's graph, the origin is at -1.
This means that, the wrong origin was used, and the actual origin is wrongly placed.
See attachment for the correction of graph A
