~~~~~~~~~~~~~~

If you are talking about an exponential function f(x), it is, probably, not f(x) = ax, but f(x) = a^x, which is f(x) = a%5Ex.

I don't like to modify author's posts, since I assume that it is the author's responsibility to provide correct input.

So, if you do agree, edit it and re-post.

f%28x%29=a%5Ex p(2,9)
9%29=a%5E2 p(2,9)
3%29=a p(2,9)
the function is
f%28x%29%29=3%5Ex which passes through point p(2,9)
here is the graph
