The graph of a function f is given. Use the graph to estimate the following:
(a) All the local maximum and minimum values of the function and the value of the local maximum (x, Y) = (-4,4) (smaller x-value)
Local maximum
(x,Y) = (6.2, Y)
(larger X-value)
Local minimum
(x,Y) = (x, Y)
(b) The intervals on which the function is increasing and on which the function is decreasing.
