Respuesta :
The Graph C which has a straight line joining the points 0, 5 and 6, 0 represents a decreasing function.
How to identify the decreasing function?
When the value of y on a graph is decreases on increasing the value of x, and vise versa, then the function is called decreasing function.
Four graphs of y against x are shown.
The graph A is a straight line joining the ordered pairs 0, 4 and 6,4. In this value of x increases from 0 to 6 while the value of y is unchanged. Thus, this is a constant function.
Graph B is a straight line joining the points 0, 0 and 6,6. This is an increasing function where the value of y increases with x.
Graph C is a straight line joining the points 0, 5 and 6, 0. In this the value of x increases from 0 to 6 while the value of y decreases from 0 to 5.
Thus, the Graph C which has a straight line joining the points 0, 5 and 6, 0 represents a decreasing function.
