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

Step-by-step explanation:
<u>A) determine the number of treatments for this study </u>

The sum of all angles in a triangle is equal to 180.
75 + 70 + 5 + 3x = 180
150 + 3x = 180
3x = 180 - 150
3x = 30
x = 10
Third angle:
5 + 3(10)
35
