The value of R (0) is undefined and the value of R (2) is 1
The x-values where R(x) = 7 are 2 < x ≤ 6
How to evaluate the functions
From the question, we have the following parameters that can be used in our computation:
The graph
To calculate R(0), we set x = 0
From the graph, we have
R(x) = undefined, when x = 0
This means that
R(0) = undefined
Also, we have
To calculate R(2), we set x = 2
From the graph, we have
R(x) = 1 , when x = 2
This means that
R(2) = 1
Also, we have
R(x) = 7
From the graph, we have
R(x) = 7 when x is greater than 2 but less than or equal to 6
This means that the values of x are 2 < x ≤ 6
