Sketch the graph of a function f(x) that satisfies the following criteria. (You do not need to define the function algebraically.)
• Defined and continuous on the interval (-5,5).
• f'(2) does not exist at 2 = 0
f(2+ h) – f(2)
• lim
< 0
h
• The slope tangent to the graph of f(x) at x = 3 is zero
• The rate of change of f(x) when x = -1 is positive
h0

Expresa commuter train leaves downtown sation and travels at a average speed of 55 miles per hour towards the north side sation, which is 50miles away. thirty minutes later, express commuter train #7 leaves north side and travels at a average speed of 35miles per hour towards downtown sation. at the moment the two trains pass each other, how far(in miles) is train #12 from the downtown sation and how long(in minutes) has the #12 train been traveling
