Answer:

I believe it is the second answer;

F(x)= (1/2)(2)^x

Step-by-step explanation:

1. the initial value is 0.5, so the first number will have to be 1/2, and it is increasing so the value of <em>b</em> must be above 1.

2. Through process of elimination, you can determine that the second equation matches the graph.

I hoped this helped! Please comment if you have any questions :)

The complex numbers corresponding to the endpoints of one diagonal of a square drawn on a complex plane are 1 + 2i and -2 – i.

kodGreya [7K]

Technically the endpoints will be intersection of first endpoint between x=1 and y=-1second endpoint between x=-2 and y=2
so they are 1-i and -2+2i
