The graph of the function f(x) = x + 2 in the given domain 0≤x≤3 is in the segment that you can see in image at the end.
How to graph the function in the given domain?
We have the linear function:
f(x) = x + 2
And we want to graph this in the domain 0≤x≤3
Let's evaluate the function in the two extremes of the domain, we will get:
f(0) = 0 + 2 = 2
f(3) = 3+ 2 = 5
So we have the segment that goes from (0, 2) to (3, 5), that will be the graph.
