For identifying the graph of each equation we can check some points , for example, the graph for the equation y= 2^x is going to be the one which has the point (0, 1) because y = 2^(0) =1. the graph with that point is the second graph
Following this procedure we find that:
- The graph for the equation y= -2^x is going to be the one which has the point (0, -1) because y = -2^(0) =-1. the graph with that point is the first graph.
- The graph for the equation y= 3*2^x is going to be the one which has the point (0, 3) because y = 3*2^(0) =3*1=3. the graph with that point is the third graph.
-The graph for the equation y= -3*2^x is going to be the one which has the point (0, -3) because y = -3*2^(0) =-3*1=-3. the graph with that point is the fourth graph.
