Next we desire to take a look at f (x ) =√x . First, note that as we don't desire to get complex numbers out of a function evaluation we ought to limit the values of x that we can plug in. We can just plug in value of x in the range as well. x ≥ 0 . It means that our graph will only present in this
To obtain the graph we'll only plug in some values of x & then plot the points.

f(x)

Then the graph is,
