y =3x ; y=3x⁴+2 ; y= 3x³-1

It looks like you have three functions defined by the equations:

1. \( y = 3x \)
2. \( y = 3x^4 + 2 \)
3. \( y = 3x^3 - 1 \)

If you need help with these functions, please specify what you're looking to do with them! Here are some possible areas of focus:

• Finding Points of Intersection: You might want to know where these functions intersect each other.
• Analyzing Functions: Finding derivatives to analyze the behavior of the functions (such as increasing/decreasing).
• Graphing: Drawing the functions to visualize their shapes.
• Finding Roots: Finding the values of \( x \) for which each function equals zero.

Please provide more details on what you're looking to achieve!
