Identify the parent function that can be used to graph the function f(x)= |4|-3
1 answer:
Answer: Option d.
Step-by-step explanation:
1. The parent function of an absolute value function is shown below:
f(x)=|x| (This is the simplest form). Because from this function we can make transformations that allow us to obtain the function f(x) = 4|x| -3
2. If you take the parent function and make y= f(x)-3/4, then you have:
y= f(x)-3/4=|x|-3/4 (The function is shifted down 3/4 units on the y-axis).
3. Then you if you make y= 4(f(x)-3/4), as following, you obtain:
y = 4(f(x)-3/4))=4|x|-3 (The function is reflected in the y-axis).
4. That is how you obtain the final function.

Answer:
Dwight will take 6 hours to finish the job alone and Joe will take 3 hours to finish the job alone.
Step-by-step explanation:
Let us assume the time taken by Dwight to split a cord of firewood = K hrs
So, the per hour rate of Dwight =
As, Joe uses 3 LESS hours then Dwight.
So, the time taken by Joe to split a cord of firewood = (K- 3) hrs
So, the per hour rate of Joe =
Now, when both of them wok together, it takes them 2 hours.
So, the per hour rate of BOTH of them =
⇒ Per hour rate of ( Dwight + Joe) =
Now, solving for the value of K , we get:
Implies either K = 6 Or K = 1
But if K = 1, (K-3) = 1- 3 = -2 hours would be A CONTRADICTION.
⇒ K = 6 hours
Hence, Dwight will take 6 hours to finish the job alone and Joe will take (k-3) = (6-3) = 3 hours to finish the job alone.
