Question

Which graph represents a decreasing function?


Graph A

Graph B

Graph C

Graph D

Answer 1

if its decreasing it would be C because your line is going down

Answer 2

Graph A represents a constant function; when x increases: y still the same (no change).

Graph B represents a growing function, when x increases , also y increases.

Graph C represents a decreasing (decay) function becasue when x increases, y decreases.

and for  Graph D, it is not even a function .


So it would be: Graph C
