Explain why the function is discontinuous at the given number a. (Select all that apply.) 1 f ( x ) = x +4 if x * -4 a = -4 if x = -4 *(-4) is defined and lim f(x) is finite, but they are not equal. O lim f(x) and lim f(x) are finite, but are not equal. x - -4+ x -* -4 O lim f(x) is not finite. x - -4 O f(-4) is undefined. none of the aboveSketch the graph of the function. 10/ 10/ 10/ 5 5 5 X X -10 -5 X 5 10 -10 -5 5 10 -10 -5 10 - 5 -5 C -10 - 10 -10 .
