3; Let f(x) { x2 + 1 ; if x < 1 ifI sx <2 be a piece-wisely defined function. if x 2. (a) Find the values for f(x) when x = 3, -2, - 1% 1 , 0, h, 1, 2, 3. (b) Sketch the graph of y = f(x). (c) State domain, range, and the x-coordinate(s) at which f(x) is discontinuous. (d) Determine the intervals where f(x) increases, decreases, and constan.
