Question

The measure of angle ø is 3pi/2. the measure of its reference angle is pi/ ?, and tan ø is ?

Answer 1

Then the vertex is at (h, k) = (2, –3) and the value of p is –3. Since y is squared and p is negative, then this is a sideways parabola that opens to the left. This puts the focus 3 units to the left of the vertex.

vertex: (2, –3); focus: (–1, –3)
