Answer:
Step-by-step explanation:
Alright, lets get started.
There is a graph given and there are four equations given.
We are asked to determine which equation belongs to this graph.
When we see the graph, We see, at x = 0, y = 1
Similarly, when x = -1, y = 0
Lets plug these conditions into the equation given:



This satisfied the condition, similarly,
Lets plug x = -1


Which satisfies the condition.
So the equation is :
: Answer A
