Answer:
A): f(x) = (x – 1)² + 2
Step-by-step explanation:
The quadratic function, f(x) = (x – 1)² + 2 is in <u>vertex form</u>: y = a(x - h)² + k, where:
- The vertex of the graph is (h,k).
- The value of <em>a</em> determines whether the graph opens up or down. If <em>a</em><em> </em>is <u>positive</u>, the graph opens up and the vertex is its minimum point. If <em>a </em>is <u>negative</u>, then the graph opens down, and the vertex is its maximum point.
- The value of <em>h</em> determines how far left or right the parent function is translated.
- The value of<em> k</em> determines how far up or down the parent function is translated.
The function, f(x) = (x – 1)² + 2, provides the pertinent information that allows us to determine the parabola's <u>minimum value</u>, as the value of <em>a</em> is a <u>positive</u>, which implies that the parabola is <em>upward facing</em>, and the vertex, (1, 2) is the minimum point.

Answer:
B is symmetric; A is not.
Step-by-step explanation:
Since you did part A, you know that the ends of each box are roughly symmetrically located with respect to the extremes of data in each case. However, the median of the data for School A is decidedly near the right end of the box; whereas the median for School B is in the center of the box.
This last fact gives the box plot for School B a symmetric appearance that is not shared by the plot for School A.

Put this into an equation such as an equation of a line.
<span>y = .43x + 20
</span><span>y = .43(6245) + 20
</span>y = $2705.35
So it will cost $2705.35 dollars. If you need help on how I got the equation let me know.
