plz complete the following question preferably before 9pm

1. a) Use the limit definition of continuity (the definition with three conditions) to discuss why a function with a jump is discontinuous at the x value of the jump. b) A function is not differentiable at a hole because the limit does not exist. True or False. Justify with an explanation and a diagram. c) If a function is differentiable at point A, then it is continuous at point A. True or false. Justify with an explanation and a diagram. Samar-DOV 2. Consider y= SQRTfX + 2) for the interval [ 2 2,] '14xl a) Determine the average rate of change. X' b) Determine, using first principles, the instantaneous rate of change equation. c) Determine the coordinate (x,y) for which the average rate of change equals the instantaneous rate of change. 3. Make up a rational function in the form y = 3/(x + a). You may use any number you like for 'a'. Determine the instantaneous rate of change equation, and then use the equation to determine the slope of the tangent at a value of x = a+1
