First of all it is always a good idea to graph a question like this one. Here are the three graphs
y = x^4 - x^2 Color: Red This is the base graph
y = x^4 - x^2 - 4 Color Blue This has - 4 added to it.
y = x^4 - x^2 + 4 Color Green This has 4 added to the base graph
Which one is correct? The red and blue one are not. The graph you want is plotted upward from the base graph. The base graph (red nothing added to it) is not right because it has points on the x axis. The graph you want does not.
The same is true of the blue graph. It cuts the x axis. That only leaves the green one.
Answer: C
Answer:
D. Both distributions are skewed left, so the interquartile range is the best measure to compare variability.
Step-by-step explanation:
Plotting the data roughly shows that the data is skewed to the left. In other words, data is skewed negatively and that the long tail will be on the negative side of the peak.
In such a scenario, interquartile range is normally the best measure to compare variations of data.
Therefore, the last option is the best for the data provided.

g(x) = 3x
g(x) = 3( x )
g( f(x) ) = 3( f(x) ) ... replace every x with f(x)
g( f(x) ) = 3( 2x-1 ) .... plug in f(x) = 2x-1
g( f(x) ) = 3( 2x) + 3( -1 ) ... distribute
g( f(x) ) = 6x - 3
You are correct in saying D is the answer
Female giraffes reach a height of 4. 3 meters, and males reach a height of 5. 5 meters. Kendra created a bar diagram and wrote an equation to find the difference in the heights, The errors made by Kendra will be that as all the numbers are put in wrong places.
Given: Kendra created a bar diagram where,
- The Top bar contains 4. 3 meters
- The Bottom bars contain d & 5. 5 meters
- Here, it is also given that, D - 5. 5 = 4. 3
Now , according to the question we will check the sample responses.In the given diagram, the numbers are jotted in wrong places .
The correct place would be as follows:-
- In the Top Bar Diagram it should be 5.5m .
- In the Bottom Bar Diagram it should be 4.3.
- One equation could be 4.3 + d = 5.5.
Therefore, The errors made by Kendra will be in equation as all the numbers are put in wrong places.
