Answer:
Step-by-step explanation:
Start with f(x) = √x.
1) Multiplying this by "c" will either stretch or shrink the graph:  stretch, if "c" is > 0; shrink, if 0 < c < 1. 
2) Replacing 'x' with 'x - h' will translate the original graph h units to the right, if h is positive; 
Replacing 'x' with 'x - h' will translate the original graph h units to the left, if h is negative.
3) Adding k to f(x) = √x will translate the graph upward by k units if k is positive and downward by k units if k is negative.

Description
In geometry, a diameter of a circle is any straight line segment that passes through the centre of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere.
