Desperate for help! I don't understand how to graph this. I'm pretty horrible at graphing. If you ever swam in a pool and your eyes began to sting and turn red, you felt the effects of an incorrect pH level. pH measures the concentration of hydronium ions and can be modeled by the function p(t) = −log10t. The variable t represents the amount of hydronium ions; p(t) gives the resulting pH level. 1.Create a graph of the pH function either by hand or using technology. Locate on your graph where the pH value is 0 and where it is 1. You may need to zoom in on your graph.

Would I make p(t)=-log10t into f(x)=-log10x Its the same thing isnt it?

That means it wants the point where y is equal to and y is equal to 1

Would that be (1,0) and (0,2)?

I believe the graph never touches those points

This is what my graph looks like.. \[F(x)=\log_{10}X\]

First isnt that negative log according to your question and the ph value is 0 and 1 when y value is 1 and 0 not the x value

Yes its negative.... So is this graph answering the question? On desmos I put y=0 and y=1 then circled the points.
