Explanation:
As with any sort of graphing problem, pick values of x and compute the corresponding value of y. Then plot those (x, y) points.
For something like this, it is convenient to choose y and then compute the value of x that goes with it.
y = 0 = √(5 -x) ⇒ x = 5 -0² = 5
y = 1 = √(5 -x) ⇒ x = 5 -1² = 4
y = 2 = √(5 -x) ⇒ x = 5 -2² = 1
y = 3 = √(5 -x) ⇒ x = 5 -3² = -4
Once you have plotted the points, draw a smooth curve through them.
