This is not in point-slope form; that applies to a line only. It is what some would call standard form for a quadratic function, and others would call vertex form.
But in this form, it is easy to see the vertex, the minimum or maximum, and the range; and it is not hard to find the intercepts. So don't bother converting (which you would do by distributing, sometimes called "FOIL"). Just use the form you were given.
Let's give it a start. What does it mean to ask for the y-intercept? What do you have to do to any function f(x) to find it?
