Consider the function f defined by \(f\left( x \right) = \left\{ {\begin{array}{*{20}{c}} {{x^2} - 1,}&{x < 3}\\ {2ax,}&{x \ge 3} \end{array}} \right.\) for all real numbers x. If f is continuous at x = 3, then value of a
Let f(x) be defined as follows: \({\rm{f}}\left( {\rm{x}} \right) = \left\{ {\begin{array}{*{20}{c}} {2{\rm{x}} + 1,{\rm{\;\;}} - 3 < {\rm{x}} < - 2}\\ {{\rm{x}} - 1,{\rm{\;\;}} - 2 \le {\rm{x}} < 0}\\ {{\rm{x}} + 2,{\rm{\;\;\;}}0 \le {\rm{x}} < 1} \end{array}} \right.\) Which one of the following statements is correct in respect of the above function?
