Question

Find the equation of f(x)=b^x given the point (2,e)

Answer 1

Don't understand what exactly you want to find. You already have an equation, no?
So only I can imagine is this
x=2 and f(x)=e
Then:\[e=b^2\]
\[b=\pm \sqrt{e}=\pm1.65\]

Answer 2

After getting b, I guess he just wants f(x) = sqrt(e)^x

Answer 3

I need to get the equation in the format of f(x)=b^x given the point (2,e)

Answer 4

That's it above in my answer.

Answer 5

The point (2,e) allows you to deduce that b = e so f(x) = e^x (sorry, I put square root before).

Answer 6

Blast, I had it right the first time.

b is sqrt e so f(x) = sqrt(e)^x.

Sorry.
