Answer:

Step-by-step explanation:
Given
x ----- y
0.5. --- 0.8
1. --- 1.6
3.--- 4.8
25. --- 40
Required
Determine the constant of proportionality
This can be calculated using the following formula:
; Where r is the constant of proportionality;
Solve for r

When x = 0.5; y = 0.8


When x = 1; y =1.6


When x = 3; y = 4.8


When x = 25; y = 40


Notice that the value of r is constant throughout;
Hence:

3x=x+3 2x=3 x=3/2
Move x terms to one side, then solve
a) f (2) = 1
b) 
c) 
<u>Step-by-step explanation:</u>
- Indicates that we have to find the inverse of the function
Given data:
--------> eq.1
---------> eq.2
To find 
Case a)
Now, substitute x = 2 in the equation 1 to find f (2)

Case b)
Now, substitute x = 1 in the equation 2 to find 

Case c)
In general,

Thereby,
