Answer:
Step-by-step explanation:
Since the vertex is right between the vertex and the directrix, the y value of the vertex must be (3+(-1))/2=1. The x coordinate will just be the same as that of the focus, or in this case 0. This means that the vertex will be at (0,1). Since the graph opens toward the focus, it will be opening up, and since its vertex is at (0,1), it will have an equation of:

1. x = 8
2.
Step-by-step explanation:
1. Solve the rational equation
First, cross multiply:
Now, use distributive property:
Separate terms with x and without x into different sides of equation:
Simplify:
Divide by -4:
2. The rational function
This rational function is undefined for all values of x, for which the denominator is equal to 0. Find these values:
This means that the line is a vertical asymptote for the rational function f(x).
