# Sketch Curve: Help Solve y=0 | Stephen

• StephenP91
In summary, the conversation discusses the method for finding points where y=0 in a given equation. The speaker seeks help in determining these points and finds a practical solution by using a graphing tool. They also mention the process of finding roots and the use of stationary points to determine the approximate value of the roots.

I have done 10)a), but b), I just can't figure it out. I am trying to find at what points y=0, but I just can't do it.

I hope someone can help me.

Thank you,
Stephen.

You've asked in the introductory physics forum rather than the math one, so you must expect to get a practical answer rather than a nice mathematical one! I suggest you type it into the grapher at

and it will show you where the zero is.

Turns out. I didn't need it. After I figured out the co-ords of the two stationary points and what happens when X gets inf and -inf then I could see what the roots were and according two the graphics I drew it's about 3.14 so I am pretty sure I didn't have to factorise that damned equation.

## What is a sketch curve?

A sketch curve is a visual representation of a mathematical function or equation, typically drawn on a coordinate plane. It helps to show the shape and behavior of the function.

## How do I solve for y=0 in a sketch curve?

To solve for y=0, you will need to find the x-intercepts of the curve. These are the points where the curve crosses the x-axis. You can do this by setting y=0 and solving for the corresponding values of x.

## What does the "Help Solve" part of the equation mean?

The "Help Solve" part indicates that this is a request for assistance in solving the equation or function. It is typically used in online forums or platforms where individuals can ask for help with mathematical problems.

## Who is Stephen?

Stephen is likely the person who posted the equation and is seeking help with solving it. It could also be a reference to a specific mathematical concept or method that can be used to solve the equation.

## Why is y=0 significant in a sketch curve?

When y=0, the corresponding points on the curve lie on the x-axis. This can provide important information about the behavior of the function, such as the number of intercepts and the symmetry of the curve.
