Which graph represents exponential decay ?

Out of those 2, the first one shows decay as it goes down from left to right.

graph 1 represents exponential decay .

Step-by-step explanation:

Given : exponential graphs .

To find  : Which graph represents exponential decay .

Solution : WE have given two  exponential graph :

we can see from graph 1 , As the values on x axis increases values on y axis decreases But in graph 2 both the values on x axis and y axis are increases simultaneously.

Therefore, graph 1 represents exponential decay .
