1. Create a graph of the pH function either by hand or using technology. Locate your graph where the pH value is 0 and where it is 1. You may need to zoom in on your graph.

Best ResponseYou've already chosen the best response.0That is something you would know, is this a question for school or what?If so you should ask your teacher if you can use a graph online

Best ResponseYou've already chosen the best response.0Ok the question says either by hand or by technology, so you're free to use any online graphing softwares

Best ResponseYou've already chosen the best response.0I was just wondering, if you could just use graphing technology instead of drawing it to make it more clear

Best ResponseYou've already chosen the best response.0So what would the graph look like?

Best ResponseYou've already chosen the best response.0dw:1438979039696:dw It would look something like this, search "graph log(x)" on google and it will generate a graph for you

Best ResponseYou've already chosen the best response.0Alright thanks. Now what about this part? 2. The pool maintenance man forgot to bring his logarithmic charts, and he needs to raise the amount of hydronium ions, t, in the pool by 0.50. To do this, he can use the graph you created. Use your graph to find the pH level if the amount of hydronium ions is raised to 0.50. Then, convert the logarithmic function into an exponential function using y for the pH.

Best ResponseYou've already chosen the best response.1First we will use the identity \(\Large y=log_b x~~means~~ x=b^y\) so if \(p(t)=y=log10(t)=log10(1/t)\) then \(1/t=10^y\) or \(t=10^{1/y}=10^{y}\) If\( y=0.5~~then~~ t=10^{0.5}\)

Best ResponseYou've already chosen the best response.0\[p(t)=\log(t)\] If you shift your t by 0.5, your graph will also change, I don't see how you could use the same graph, you would need to shift it slightly\[p(t+0.5)=\log(t+0.5)\]

Best ResponseYou've already chosen the best response.0yes you are wrong, what I mean by in that table is \[\log_{10}(2)=0.3010\]

Best ResponseYou've already chosen the best response.0Last one! The pool company developed new chemicals that transform the pH scale. Using the pH function p(t) = −log10t as the parent function, explain which transformation results in a yintercept and why. You may graph by hand or using technology. Use complete sentences and show all translations on your graph. p(t) + 1 p(t + 1) −1 • p(t)

Best ResponseYou've already chosen the best response.1Check: p(10^0.5)=log10(10^0.5)=(0.5)=0.5

Best ResponseYou've already chosen the best response.1g(x)=f(x)+k will translate the graph of f(x) vertically (shifts up by k) g(x)=f(xh) will translate a graph of f(x) horizontally to the right by "h". which implies g(x)=f(x+h) will translate graph of f(x) to the left by h. g(x)=f(x) will flip the graph about the xaxis. So make your choice according to the requirements.

Best ResponseYou've already chosen the best response.1You have already graphed p(t) at the very beginning.dw:1438979941325:dw You will have to figure out which translation will result in a yintercept!
