Let \( f \) be the function defined as follows: \[ f(x) = \begin{cases} |x - 1| + 2, & \text{for } x < 1 \\ ax^2 + bx, & \text{for } x \geq 1 \end{cases} \] where \( a \) and \( b \) are constants. ### Questions a) If \( a = 2 \) and \( b = 3 \), is \( f \) continuous for all \( x \)? Justify your answer. b) Describe all values of \( a \) and \( b \) for which \( f \) is a continuous function. c) For what values of \( a \) and \( b \) is \( f \) both continuous and differentiable?
