What is the first step in writing an equation for a parabola in conic sections?

• Identify the focus and directrix

• Plot the given information on a graph

• Determine the axis of symmetry

• Simplify the equation

Why is it important to write down the equation once you determine the axis of symmetry?

• To avoid using a calculator

• To make the graph look neat

• To check for errors in the graph

• To ensure you remember the equation

What is a common mistake students make when determining the value of P?

• Not simplifying the equation

• Confusing the focus with the directrix

• Forgetting to plot the vertex

• Using the wrong sign for P

How do you determine the value of H in the equation X - H^2 = 4PY?

• H is the opposite of the number next to Y

• H is the same as the coefficient of X

• H is the opposite of the number next to X

• H is the same as the number next to Y

What does a positive value of P indicate when the axis of symmetry is vertical?

• The parabola opens downwards

• The parabola opens upwards

• The parabola opens to the right

• The parabola opens to the left
