Solve the problem.Why can't 1 be the base of a logarithmic function?
What will be an ideal response?
Answers may vary. One possibility: If the base of a logarithm were 1, as in y = log1
, then for all values of y, x would equal 1. A function requires each x-coordinate to have a unique y-coordinate. Thus, the equation y = log1
, whose graph would be equivalent to the line 
would not be a function.
