Answer:
BC = 3 units
Step-by-step explanation:
Given points:
- A = (2, -2)
- B = (-4, -4)
- C = (-4, -1)
- D = (-2, 3)
- E = (1, 3)
- F = (2, 5)
<u>Plot the points</u> on the coordinate plane (x, y) and connect them in alphabetical order with straight lines (see attached).
From visual inspection of the <u>drawn polygon</u>, we can see that the length of BC is 3 units.
It is fairly simple to calculate the length of BC without plotting the points.
As points B and C have the same x-value, this means that the distance between them is simply the difference between their y-values.
⇒ distance = |-4 - (-1)| = |-3| = 3 units

<h3>What are piecewise functions?</h3>Piecewise functions are functions that have at least 2 sub functions, each of which have different intervals
The function is defined by
The first function in f(x) is defined by
See attachment for the graph of the first function
<h3>(b) Graph the second function</h3>The second function in f(x) is defined by
See attachment for the graph of the second function
