The function ( f(x) = x^2 + 5 ) is a quadratic function that opens upwards, with its minimum value occurring at the vertex. The vertex is at the point (0, 5), which is the lowest point on the graph. Since ( x^2 ) is always non-negative, the function's output will always be greater than or equal to 5. Therefore, the range of the function is ( [5, \infty) ).

The MIN Function determines the lowest number in a range
A number does not have a range and domain, a function does.
The range is y >= 5.
a function whose range is in the real number
The "maximum" function.
the range is a positive real number

The AVERAGE function.
Countblank function is a derivative of count function and it is doing a very simple task - countblank function counts the number of cells in the range with no data. Actually, if you'll add the results for count/a function and countblank function you'll get the total number of cells in the range (empty and not).
