Q#1: The flow of current is given as under: () = {
^2 + 1, 0 ≤ < 1
2, 1 < ≤ 2
^3 − 4, > 2
Where t is the time in seconds. Interpret the current flow
continuous at = 1 and also predict the value of current at
= 5 seconds.

Q#2: Using Implicit Differentiation technique, Solve:
i) − − − = 1
ii) ^2 + ^2 =(+)/(x-y)

function. If there is a point of inflection, Find it.
