Question

Which equation describes the asymptote of the exponential function represented by this graph

Answer 1

Given: The graph of an exponential function.

Required: To find the equation of the asymptote of the exponential function.

Explanation: The exponential function of the type

`y=a(b^x)+c`

Has the horizontal asymptote at y=c.

From the given graph, we can see that as x tends to negative infinity, the curve tends to

`y=4`

Final Answer: Option A is correct.
