Functions can be represented using equations, graphs and tables.
The function is given as:

When l = 1, we have:


When l = 2, we have:


When l = 3, we have:


When l = 4, we have:


Represent the above results as a table, we have:
<u>l a(l)</u>
1 0.5
2 2.0
3 4.5
4 8.0

Electronegativity<span> is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most</span>electronegative<span> element) is assigned a value of 4.0, and values range down to caesium and francium which are the least </span>electronegative<span> at 0.7.</span>
Negative x positive = negative
Negative x negative = positive
-4 x 8 = -32
-4 x -1 = 4
-4 x -5 = 20
-4 x 9 = -36
Answer: |-32 4 20 -36|
