Sketching the graph of the function f(x)
From the question, we have the following parameters that can be used in our computation:
(2,3), (4,5) and (6,7).
From the above, we can see that
The y values are greater than the x values by 1
This means that the equation of the function is
y = x + 1
So, we plot the graph of the function y = x + 1 for the equation of the function that passes through (2,3), (4,5) and (6,7).
