First we can simplify f(x) to make it a little easier. We can write it as
4x^3+2x^2-7x+4 by combining like terms

The we just subtract g(x) from f(x) and simplify
4x^3+2x^2-7x+4-(5x^3-7x+4) and remember to distribute the negative to g(x)
4x^3+2x^2-7x+4-5x^3+7x-4 (combine like terms)
-x^3+2x^2
In factored form, this becomes
-x^2(x-2)

Hope this helps

Which of the following can be determined from a box-and-whisker plot?
elixir [45]
<h3>Answer: B) Median</h3>

The middle vertical line inside the box is the median or the value of Q2. The term "median" is used more often instead of Q2, but your book may use this terminology as well.

---------------

side notes:

* The left and right edges of the box are Q1 and Q3 respectively

* The IQR (interquartile range) is found by subtracting Q3 and Q1

* The min and max are the left and right most edges of the the whiskers, this is assuming there are no outliers

* There is no way to get the mean or mode from a box and whisker plot alone.

* The term "average" is too vague and could refer to mean, median, or mode.

MATH ............................................
Aneli [31]

It must be true that a implies c, because of the transitive property.

If a is true, then b is true as well. But every time b is true, c is true as well.

So, "jumping" over b, we have that if a is true, c is true as well.

Think of this example:

  • a: I live in Rome
  • b: I live in Italy
  • c: I live in Europe

It is true that a\implies b, because Rome is inside Italy, and similarly b\implies c, because Italy is a European state.

So, if I live in Rome, I must live in Europe as well.
