I am working on algebraic functions and I am stuck on this problem:
$f(x) = a * r^x$
This would be a simple problem if it weren't for that $1.5$ -
[I also solved for $3,1.5$]
So, this is where I get stuck every time.
I have tried solving it multiple ways but it always ends up to the same effect, where $r$ is always $=$ to something funny that is unsolvable - at least for me.
Could someone explain how you got your answer so that I can understand the process? I know how to do this type of problem, but it is just this one that I can't get!!!!
Thanks for your help and time!
EDIT: I need this simplified, that is why I cant leave $r^2 = 1.5$
