Answer:

2. $f(x) = abs(3-x) + 4$

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Graphing Functions.

From the graph we can see that the initial starting position of y is 4 , so the static number in the function will be +4. <u>V-shaped graphs</u> are the result of <u>absolute values</u> therefore the variable will be inside an absolute value indicator. Lastly, since the starting position of x is +3, then x is being subtracted from 3 in order for the absolute value to be 0. Therefore the answer is ....

$f(x) = abs(3-x) + 4$

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Studentka2010 [4]

The experimental units in this experiment are the 10 plants in group 2.

The experimental unit is a term used in science to refer to an individual or group of objects that are initially equivalent and then undergo experimental processes.

According to the above, the experimental unit of this experiment is the group 2 of plants because these are the plants that are going to be put into experimentation with a new fertilizer.

Then, the answer is D, because it refers to the experimental unit corresponding to this experiment.

The product of two positive integers is 176. One number is 5 more than the other. Find the smaller number.

svlad2 [7]

Hello from MrBillDoesMath!

Answer:

Discussion:

Let "n" be the smaller number. Then

n * (n+5) = 176.

My first reaction to this problem was to factor 176 in my head. That's 176 = 16 * 11 and 16 is 5 more than 11. So that's the solution!.... Now let's solve it using the brute force approach:

n(n+5) = 176 =>

n^2 + 5n - 176 = 0 => use the quadratic formula

n = ( -5 +\- sqrt( 5^2 - 4(1)(-176)) ) /2

= ( -5 +\- sqrt( 25 + 704) )/ 2

= ( -5 +\- sqrt (729) ) /2 => as sqrt(729) = 27

= (-5 +\- 27) / 2 =>

= (-5 + 27)/2 or ( -5 -27)/2 =>

= 22/2 or -32/2 =>

= 11 or -16

But -16 is not allowed as the question wants a positive value.

Thank you,

MrB
