Use the graph to answer the question. For which value of a is x) discontinuous? O A. - 1 O B. O O C. 4 O D. 6The following function is continuous at all points in the domain of real numbers. What is the value of n? [2x +2, ifx >n f (x) = 4x, if x Sn O A. -1 O B. O O C. O D. 1Which statement correctly describes the function? x+4 f (x) = x~+7x+10 O A. It is continuous. O B. It is discontinuous because there is a value a for which f (a) is not defined. O C. It is discontinuous because there is a value a such that lim f(x) # f(a). O D. It is discontinuous because there is a value a such that lim f(x) does not exist.-4x+3, if x$1 Determine whether the function f (x) = x -3, ifx>1 is continuous or discontinuous. If it is discontinuous, state why it is discontinuous. O A. It is continuous. O B. It is discontinuous because there is a value a for which f (a) is not defined. O C. It is discontinuous because there is a value a such that lim f(x) # f(a) . x ->a O D. It is discontinuous because there is a value a such that lim / (x) does not exist
