Question

I really need help with Logarithmic Functions. I don't understand how to graph them correctly. My question is posted below.

Answer 1

If you have ever swum in a pool and your eyes began to sting and turn red, you are aware of the effects on an incorrect pH level. The pH level measures the concentration of hydronium ions and can be modeled by the function p(t) = –log_10 t. The variable t represents the amount of hydronium ions, and p(t) gives the resulting pH level.

Water at 25 degrees Celsius has a pH of 7. Anything that has a pH lower than 7 is called acidic, while pH's above 7 are basic or alkaline. Seawater has a pH just over 8, while lemonade has a pH of approximately 3.
1. Create a graph of the pH function. Locate on your graph where the pH value is 0 and where it is 1. You may need to zoom in on your graph.

Answer 2

I understand how to find what t is when -log_10 t is equal to 0 and 1. I just have no idea how to graph it. I am so lost and have no one to help.

Answer 3

Try graphing the old-fashioned way.
Make a table of points and graph the points.

Answer 4

I don't understand how to make an accurate graph when graphing the points of logarithmic functions.
