Explain why the function is discontinuous at the given number a. Select all that apply. fx= beginarrayl frac x2-5xx2-25ifxneq 5 1ifx=5endarray . a=5 f5 is undefined. limlimits _xto 5fx does not exist. limfx and limlimits _xto 5-fx are finite, but are not equal. xto 5 ° r5 is defined and limlimits _xto 5fx is finite, but they are not equal. none of the above Sketch the graph of the function.
