3. use a graphing utility to find the points of intersextion of the circle and the parabola given by xSquared+ySquared-5x+4y-13=0 and y=xSquared-3x+2

4. The market equilibrium of a commodity is the quantity (and corresponding price) at which the supply of the commodity and the demand for the commodity are equal. The supply and demand curves for a business dealing with wheat are

Supply: p=1.45+0.00014xSquared

Demand: p=(2.388-0.007x)Squared

where p is the price (in dollars per bushel) and x is the quantity (in bushels per day). Use a graphing utility to graph the supply and demand equations in the same viewing window and find the market equilibrium. (Hint: the market equilibrium is the point of intersection of the graphs for x>0.)
