Question

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.

Answer 1

do you have a graphing calculator with you ?

Answer 2

No but I can use the internet for one.

Answer 3

use this one a plug in your equation https://www.desmos.com/calculator

Answer 4

Thank you its my go to already! c:

Answer 5

Would I make p(t)=-log10t into f(x)=-log10x

Its the same thing isnt it?

Answer 6

Yep same thing

Answer 7

Wow so thats all I have to do to graph it?

Answer 8

"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 9

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

Answer 10

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

Answer 11

give me a sec

Answer 12

Is Ph the P(t)

Answer 13

Yes.

Answer 14

@denonakavro

Answer 15

I believe the graph never touches those points

Answer 16

This is what my graph looks like..

\[F(x)=\log_{10}X\]

Answer 17

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

Answer 18

Yes its negative....

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