Use the figure below, which gives a graph of the function , to give values for the indicated limits. If a limit does not exist, enter none.
graph of a piecewise defined function, which is an upward opening quadratic function, with vertex at (0,-10), for x in [-3,1]. the function is a line with slope 4 for x greater than 1, starting with an open circle at (1, 5). there is a hole in the line at x=4, and a point plotted at (4, 18).
(a) = help (limits)
(b) =
