Given the two points: (270, 59) and (420, 135) I want to find an exponential function that goes trough these two points.(adsbygoogle = window.adsbygoogle || []).push({});

So I have:

[itex]ca^{260} = 50[/itex] and [itex]ca^{420} = 135[/itex]

I then divide these two functions:

[itex]\frac{ca^{270}}{ca^{420}} = \frac{59}{135}[/itex]

[itex]a^{270-420} = \frac{59}{135}[/itex]

[itex]a = (\frac{59}{135})^{\frac{1}{270-420}}[/itex]

Is this the correct way for finding a and c, thus giving me a eksponential function?
