Answer:
Simplest function is f(x) = 2x - 1
Step-by-step explanation:
When a function has a zero, simply put, that point is where the graph goes through the x-axis. At this point, the y value is 0.
If a function has a 0 of 1/2, that translates to x = 1/2 and also (1/2, 0). That means that y = 0 when x = 1/2.
If x = 1/2 and is a zero, then x - 1/2 = 0 and 2x - 1 = 0 (notice that y = 0 here and solving for x would get you right back to x = 1/2).
The simplest function with a zero of 1/2 is
f(x) = 2x - 1
You know it is true that the zero is 1/2 for two reasons. First one is to set the right side equal to 0 and solve for x.
The second one is to graph the line y = 2x - 1 and see that it goes through the x axis at 1/2 where y = 0.

Answer:
The difference between the number of pages that Darla and Juan read are <u>VI pages</u>.
Step-by-step explanation:
Given:
Darla told her teacher that she had read XLV pages in her library book.
Juan said that he had read XXXIX pages.
Now, to get the difference between the number of pages that Darla read and Juan read.
As, we see the number of pages are in roman numeral symbols.
So, we convert them in numbers first to calculate:
Darla read = XLV pages.
Darla read = 45 pages.
Now,
Juan read = XXXIX pages.
Juan read = 39 pages.
So, to get the difference between the number of pages by subtracting:

<em>Thus, the difference between the number of pages = 6 pages.</em>
Now, converting it into roman numerals:
6 pages = VI pages.
Therefore, the difference between the number of pages that Darla and Juan read are VI pages.
