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,

To find the slope(m), you use the slope formula:
And plug in the two points
(x₁ , y₁) = (1, 0)
(x₂ , y₂) = (5, 3)
