Question

The question is attached below. I literally have no clue. What is the A, B, a, and x supposed to represent? I want to know how to do future problems like this.

Answer 1

A,B, and a are all just numbers. Let's work through each of these to see if they fit the pattern.

A+Ba^x

If A <0, B>0, and 0<a<1, what does this actually describe?

Well, since a is between 0 and 1, as x gets larger, the value of a^x gets smaller and smaller. B is positive, so we'd be adding less and less to a negative value (A) as x gets larger. Is this what's happening in the graph?

Answer 2

The graph is going like this:
