pH = f(x) = -log₁₀x
1. Graphs
I used Excel to calculate the pH values and draw the graphs (see the Figure).
f(x) and f(x) +1 are plotted against the left-hand axis, while f(x+ 1) is plotted against the expanded right-hand axis.
The points at which pH = 0 and pH = 1 are indicated by the large red dots.
2. x = 0.5
When x = 0.5, pH ≈0.30. The point is indicated by the red diamond.
3. Transformations
(a) ƒ(x) = -log(x) + 1
This function has no y-intercept, because log(0) is undefined.
(b) ƒ(x +1) = -log(x + 1)
f(0) = -log(0 + 1) = -log(1) = 0
This function has a y-intercept at (0,0).
hope this helps please mark me brainliest!

hope this helps! :o)
Step-by-step explanation:
48 ounces give you 3 pounds.
By multiplying the same numbers.
2*2=4 *4 square root is 2
3*3=9 *9 square root is 3
4*4=16 *16 square root is 4
5*5=25 *25 square root is 5
Try this, maybe it will work :)
Answer:
Step-by-step explanation:
Assumed the question is how many pages are in each chapter.
<u>Let it be x:</u>
- 6x + 8 = 194
- 6x = 186
- x = 186/6
- x = 31
