Question

write an exponential equation from two points. (3, 1.5) (4, 15)

Answer 1

So you have
\[y = Ae^{Rx}\]

Taking each x,y pair and plugging into that equation will give you two equations you can use to find A and R

Answer 2

um the equation my teacher gave me was y=ab^x. I got the answer of y=.0015(10)^x and I was just checking to make sure it was correct. :0]

Answer 3

Ok. Your b = My e^R.

\[1.5 = ab^3\]
\[15 = ab^4\]

Dividing them we have
\[\frac{15}{1.5} = \frac{ab^4}{ab^3} \rightarrow 10 = b\]
Then plugging back in for b we have
\[1.5 = a(10)^3\rightarrow 0.0015 = a\]

So yeah
\[y = .0015(10)^x\]
