Find f(x) and g(x) so that the function can be described as y = f(g(x)). (5 points) y = eight divided by square root of quantity
zubka84 [21]

Answer:

  • f(x) = 8/√x
  • g(x) = 2x+4

Step-by-step explanation:

For this sort of problem, there can be an infinite number of answers.

It can be convenient to choose one of the simpler answers by looking at the operations that are performed on the variable. Here, you have ...

  • 2 multiplies it
  • 4 is added to the product
  • the square root is taken
  • 8 is divided by that root

You can work from the bottom up and define the outer function (f(x)) to be any of these operations. In our answer above, we have elected to include the "square root" and the "8 divided by that root" in our definition of f.

Then our function g takes care of the other operations.

What is the interquartile range of 45,60,40,90,60,50,75,120,90
puteri [66]
IQR = 40

1) Put the numbers in order: 40, 45, 50, 60, 60, 75, 90, 90, 120
2) Find the median: Median is 60 (the 2nd one)
3) Place parentheses around the numbers above and below the median. For easy identification of Q1 and Q3. (40, 45, 50, 60,) 60, (75, 90, 90, 120)
4) Find the Q1 and Q3. Q1 = median of the lower half of the data; Q3 = median of the higher half of the data. Q1 and Q3 have even sets so its median cannot be defined.
5) Had both sets contain odd sets, the median of Q1 is subtracted from the median of Q3 to get the IQR.

We can then use the Alternative definition of IQR.
IQR is the difference between the largest and smallest values in the middle 50% of a set data.

40, 45, 50, 60, 60, 75, 90, 90, 120

Middle 50% is 50, 60, 60, 75, 90; IQR = Largest value - smallest value;

IQR = 90 - 50 = 40

Create a cubic function that is not the parent function.
salantis [7]

Answer:

Below.

Step-by-step explanation:

One is (x - 3)^3.

The graph of the parent function x^3 rises from the lower left quadrant and there is a point of inflection through (0, 0),  then it rises to the right in the first quadrant.

The graph of  (x - 3)^3 is the translation of the graph of x^3,  3 units to the right. It will pass through the x-axis at (3, 0).

Determine whether the relation shown in the table is a direct variation, and inverse, or neither.
Grace [21]
The table of values has an inverse relationship. An inverse relationship is a relationship in which changes in one set of values causes changes in another set of values in the other direction. Simply saying, if a set of values (x) increases, another set of values (y) decreases.
