In summary, to show that the point (p, 4p^2) lies on the curve y = 4x^2 for all real values of p, you can substitute p into the equation and see that it satisfies the equation. This means that (p, 4p^2) is on the graph.

Show that the point [tex](p, 4p^{2})[/tex] lies on the curve [tex]y = 4x^{2}[/tex] for all real values of p.

I'm not at all sure how to go about answering this. I know that substituting p into [tex]y = 4x^{2}[/tex] satisfies the equation. Is that enough?, or I'm not looking at this deep enough. Any hint(s) appreciated.

Thanks.

Saying a point is on the graph given by some equation, you are saying the x- and y-coordinates satisfy that equation. So yes, since substituting x = p into your equation gives y = 4p^2, you know that [itex] (p, 4p^2)[/itex] is on the graph.

Looks like the question wasn't as difficult as I thought it was going to be.

Okay statdad thanks. :)

P.S. Appologies to moderators. I'll post these sorts of questions in the correct section next time. ;)
 

FAQ: Point (p, 4p²) on Curve y = 4x² for All p

What is the equation of the curve y = 4x²?

The equation of the curve is y = 4x², which is a quadratic function. This means that the graph of the curve will be a parabola.

What is the significance of the point (p, 4p²) on the curve?

The point (p, 4p²) is significant because it is a point that lies on the curve y = 4x² for any value of p. This means that for any value of p that is plugged into the equation, the point (p, 4p²) will be a solution to the equation.

How does the value of p affect the position of the point (p, 4p²) on the curve?

The value of p affects the position of the point (p, 4p²) on the curve by determining the x-coordinate of the point. As p increases, the x-coordinate will also increase, resulting in a point that is further to the right on the curve.

Is the point (p, 4p²) the only point on the curve y = 4x² for any given value of p?

No, the point (p, 4p²) is not the only point on the curve for any given value of p. There are infinitely many points on the curve, as it is a continuous function. However, the point (p, 4p²) is a special point that will always lie on the curve for any value of p.

How can the equation y = 4x² be used to find the coordinates of other points on the curve?

The equation y = 4x² can be used to find the coordinates of other points on the curve by plugging in different values for x and solving for y. For example, if x = 2, then y = 4(2)² = 16. This means that the point (2, 16) lies on the curve. By plugging in various values for x, we can find the coordinates of other points on the curve.
