Which exponential function/geometric sequence matches the graph?
a) y = -1/2x
b) y = 1/2x
c) y = -2^x
d) y = 2^x

Option D is the correct option.

Step-by-step explanation:

In the given question we have to identify the exponential function/geometric sequence matches the graph.

Since Options A and B are the equations of a straight line.

Option C is starts with negative notation that means the given function when graphed it's on the negative side of the y axis.

Now last option D which is in the form of .We find the points lying on the graph will be (0, 1), (1, 2), (2, 4) which are mentioned in the graph.

We conclude option D is the answer.

range is infinite on both x and y axis positive and negative
