H-E-L-P!
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 translations on your graph.

• p(t) + 1
• p(t + 1)
• –1 • p(t)

use this online graphing calculator to see what happens parent: y = -log(t) graph 1: y = -log(t) + 1 graph 2: y = -log(t + 1) graph 3: y = -1 x -log(t) https://www.desmos.com/calculator hope it helps....

Thanks! I'll try it out, but how will I know which one will result in a 'y-intercept'?
