Answer:
4. 48, 24, 12
21. A, B, B, C
Step-by-step explanation:
There are two different questions here. One where you get to make up an exponential function and write a table of values. The other is a statistics problem in which you compare 5-number summaries.
__
<h3>Exponential Function</h3>For the function f(x) = a·b^x, the value of f(0) is 'a'. The given table shows a=96. The only requirement for choosing 'b' is that it not be 1. We can choose b=1/2, and our table will be ...
y = 96·(1/2)^x
For each increase of x by 1 unit, the value of y is cut in half.
__
<h3>Statistics</h3>The attachment shows you how to find the answers to the questions.
The median is the bar in the middle of the box. The values for the different teams are ...
- A: 78
- B: 86
- C: 82
Team A has the lowest median; Team B has the highest median.
The interquartile range (IQR) is the length of the box. For the different teams, the values are ...
- A: 88-74 = 14
- B: 90-78 = 12
- C: 86-70 = 16
Team B has the smallest IQR; Team C has the largest.

The standard form of the parabola is x = -4/3y² -40/3y -103/3
What is parabola?
A parabola is an approximately U-shaped, mirror-symmetrical planar curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. One way to describe a parabola is with a point and a line.
x = -4/3(y +5)² -1
Solve for x.
x = (4y² +40y +103)/(-3)
x = -4/3y² -40/3y -103/3 . . . . 'standard form' in the US
__
Taking our clues from the graph*, we can write the vertex form equation as ...
x = -4/3(y +5)² -1 . . . . . . 'standard form' in other places
____
* The vertex is (-1, -5), so for some leading coefficient, the equation will be ...
x = a(y -(-5))² +(-1) = a(y +5)² -1
The value of 'a' is the scale factor. Here, that is the difference between the parabola value (x = -2 1/3) and the vertex value (x = -1) one unit away from the vertex.
