Learn how to graph a parabola with the vertex and the origin conics

The video tutorial explains how to analyze and graph parabolas, focusing on the equation y^2 = 4x. It covers the orientation of the graph, identifying the vertex and focus, calculating the value of P, and understanding the directrix and line of symmetry. The tutorial emphasizes the importance of knowing how a parabola opens and provides tips for plotting the vertex and focus accurately.

What is the orientation of the graph for the equation y^2 = 4x?

• It opens vertically.

• It opens horizontally.

• It opens diagonally.

• It does not open.

In the equation y^2 = 4(x - h), what do the values of h and k represent?

• They are the coefficients of x and y.

• They determine the width of the parabola.

• They represent the slope of the line.

• They are the coordinates of the vertex.

How can you find the value of P in the equation 4P = 4?

• Multiply both sides by 4.

• Subtract 4 from both sides.

• Divide both sides by 4.

• Add 4 to both sides.

What is the relationship between the focus and the vertex of a parabola?

• The parabola opens away from the focus.

• The parabola opens towards the focus.

• The focus is always below the vertex.

• The focus is always above the vertex.

How is the directrix related to the line of symmetry of a parabola?

• The directrix is the same as the line of symmetry.

• The directrix is perpendicular to the line of symmetry.

• The directrix is parallel to the line of symmetry.

• The directrix is not related to the line of symmetry.
