Evaluate the limit by calculating the left-hand and the right-hand limits at x = 7. If the limits are infinite, enter co or -co. 2x lim x- 7 2x lim = X-+7 x - 7 Given the calculations of the right-hand and the left-hand limits, select the correct conclusion about lim 2x x-7x-7 The limit exists because lim 2x x-7x-7 = L, for some real number L. The limit does not exist because lim 2x is undefined. X-7x-7 The limit does not exist and the function decreases without bound as x approaches 7. The limit does not exist and the function increases without bound as x approaches 7
