Explain why the function is discontinuous at the given number a. (Select all that apply.) f( X ) = _ a=5 x + 5 Of(-5) is undefined. lim f(x) and lim f(x) are not finite, and are not equal. x 4-5+ X- -5 [ lim f(x) does not exist. x - - 5 x - - 5 Of(-5) and lim f(x) are finite, but are not equal. O none of the above Sketch the graph of the function. 2 10 5 10 10 -5 -2 2
