Write an equation for the function graphed. Show the work to find the value of a Solution 22)roots are x =0,3 numerator has x(x-3) vertical asymptotes at x =-3 , x=4 denominator has (x+3)(x -4) function is of the form y =a[x(x-3)]/[(x+3)(x -4)] horizontal at y =-2 limx-->infinitya[x(x-3)]/[(x+3)(x -4)] =2 limx-->infinitya[x2(1-(3/x))]/[x2(1+(3/x))(1 -(4/x))] =2 =>a[(1-(0))]/[(1+(0)(1 -(0))] =2 a =2 function is y =2[x(x-3)]/[(x+3)(x -4)].
