Is the function given below continuous at x = 4? Why or why not? f(x) = 7x - 4 Is f(x) = 7x - 4 continuous at x = 4? Why or why not? O A. Yes, f(x) is continuous at x = 4 because f(4) exists. O B. Yes, f(x) is continuous at x = 4 because lim f(x) is equal to f(4). X->4 O C. No, f(x) is not continuous at x = 4 because lim f(x) and f(4) do not exist. X-> 4 O D. No, f(x) is not continuous at x = 4 because lim f(x) is not equal to f(4). X-14
