Question \#1: An economist has estimated that the demand curve and supply curve for bonds can be estimated using the following equations: Demand: \( P=-0.4 Q+940 ; \) Supply: \( P=Q+380 \) A. What is the equilibrium price and quantity of bonds in this market? B. At \( P=\$ 800 \), is there be a shortage or surplus? By how much? C. Suppose that the government impose a tax on the bond market that leads to decrease supply by 70 units at each price level, what is the new equilibrium price and quantity?

Graph the polynomial function \( f(x)=(x+4)(x-1)(x+6) \) using parts (a) through (e). The \( y \)-intercept is -24 . (Simplify your answer. Type an integer or a fraction.) (c) Determine the zeros of the function and their multiplicity. Use this information to determine whether the graph crosses or touches the \( x \)-axis at each \( x \)-intercept. The zero(s) of \( f \) is/are \( -4,1,-6 \). (Simplify your answer. Type an integer or a fraction. Use a comma to separate answers as needed. Type each answer only once.) The least zero is a zero of multiplicity 1 , so the graph of \( f \) crosses the \( x \)-axis at \( x=-6 \). The middle zero is a zero of multiplicity 1 , so the graph of \( f \) crosses the \( x \)-axis at \( x=-4 \). The greatest zero is a zero of multiplicity 1 , so the graph of \( f \) crosses the \( x \)-axis at \( x=1 \). (d) Determine the maximum number of turning points on the graph of the function. \( \square \) (Type a whole number.)
