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.
(Hint: You may use GeoGebra or other graphing software if you like!)

2. The pool company has developed new chemicals that transform the pH scale. Using the pH function: p(t) = –log10 t as the parent function, explain which transformation would result in a y-intercept. Use complete sentences and show all three translations on your graph.

• p(t) + 1

• p(t + 1)

• –1 • p(t)
