For each graph:

(a)y=2x4+36x2+34 4x4

(b)y=x242x

perform the following

• Give the Domain
• Find the X and Y intercepts ( estimate to 1 decimal place if needed). E.G. evaluate the function at a series of points.
• Discuss symmetry - if any
• Find the asymptotes- if any
• Find the intervals of increase or decrease
• Find all local maxima and minima and clearly denote them
• Find the points of inflection and regions of concave UP and concave DOWN
• Give a rough sketch of the curve- by hand or software if you prefer. E.g., evaluate at a set of points and fill in the graph.
