Question 841236
Plot the points on graph paper, but FIRST, TAKE THE LOGARITHMS OF THE y-coordinate VALUES!  Pick either base e or base 10, one or the other; not both.  You are looking for a line this way:


(Using Natural Logs as an example)
Imagine you have ordered pairs of the form, (x,y).
{{{y=ae^(kx)}}}
{{{ln(y)=ln(ae^(kx))}}}
{{{ln(y)=ln(a)+kx*ln(e)}}}
{{{ln(y)=ln(a)+kx}}}
{{{highlight(highlight(ln(y)=kx+ln(a)))}}}
This is a linear equation, and your set of points might very well fit this model.  The vertical axis is for {{{ln(y)}}}, the horizontal axis is  for x values, the slope is {{{k}}}, and the vertical axis intercept is {{{ln(a)}}}.


When you then want this back in the form of an exponential equation, setup your ln(y) equation with the k and intercept you found, and work backward using algebraic steps toward getting y as a function of x.
---- Better yet, once you have the values, just use them to directly form the exponential equation.
