Question

This is the graph of f(x)=-2 x (1/2)^x. What is the horizontal asymptote of f(x)?

Answer 1

We are given the following function:

`f(x)=-2((1)/(2))^x`

This is a function of the form:

`f(x)=a(b)^x`

For this type of functions the horizontal asymptote is located at:

`y=0`

The graph of the function is:
