Different values of b.
<h3>Answer: There is no logarithmic function whose graph goes through given points.</h3><h3 />
Maybe the second point is ![\left(\dfrac{1}{16},\ 2\right)](https://tex.z-dn.net/?f=%5Cleft%28%5Cdfrac%7B1%7D%7B16%7D%2C%5C%202%5Cright%29)
Substitute:
![\log_b\dfrac{1}{16}=2\to b^2=\dfrac{1}{16}\to b=\sqrt{\dfrac{1}{16}}\to b=\dfrac{1}{4}](https://tex.z-dn.net/?f=%5Clog_b%5Cdfrac%7B1%7D%7B16%7D%3D2%5Cto%20b%5E2%3D%5Cdfrac%7B1%7D%7B16%7D%5Cto%20b%3D%5Csqrt%7B%5Cdfrac%7B1%7D%7B16%7D%7D%5Cto%20b%3D%5Cdfrac%7B1%7D%7B4%7D)
<h3>Then we have the answer:</h3>
![\boxed{y=\log_{\frac{1}{4}}x}](https://tex.z-dn.net/?f=%5Cboxed%7By%3D%5Clog_%7B%5Cfrac%7B1%7D%7B4%7D%7Dx%7D)
I'm not sure about the answer but you could try drawing it how it describes it. It may help you picture it better. Sorry I couldn't be any more help but that's what I would try
Z would be 3 because 10*3 is 30 and 30-2 would be 28 :)
I think this is fake but ima say my answer anyway subtract 17 by 14 and u have ur answer I think I don't think this is a math question but, little tiny tottie Middle schoolers have it different in highschool so I don't know.
