F(x) =a (x-b) /(x-c )(x-d)
Vertical asymptote : x =1; therefore c = 1
therefore F(x) = a(x-b)/(x-1)
2. horizontal asymptote y = -3
x -intercept at (1/2; 0) , so b = 1/2 , then F(x) = a(x-1/2) ( x-1)
the graph passes through (0;-1) , so finding a :
-1 = a(0-1/2)/ (0-1) ';
-1(-1) = -1/2 a therefore a = -2* (1) ; so a = -2
so the graph will be y = -2 ((x-1/2) / (x-1)
