1. The question is :

f : x → ae x + a, x ∈ . Given that a is a positive constant, a sketch the graph of y = f(x), showing the coordinates of any points of intersection with the coordinate axes and the equations of any asymptotes.

I got the graph and its intersection correct but can someone explain why the equation of the asymptote is y=a.
2. Noticed for the graph of the exponential where as you go further left (negative x direction), e^x gets closer to 0?

Note that for:

then:

So for:
