Step 1

- a) Given equation of parabola is

The standard equation of a right-left parabola with vertex at (*h*,*k*) and focal length *p* is given by:

Rewriting the given equation:

Here *h* = 3, *k* = -1 and *p* = 4

Hence the vertex is (*h*,*k*) = (3, -1)

And the focus is given by (*h* + *p*, *k*) = (3 + 4, -1) = (7,-1)

The directrix is given by *x* = *h* – *p*

Hence, the directrix is *x* = 3 – 4 = -1

Step 2
