also i do not know how to do this. use the definition of the derivative to show how the formulas in are obtained.

If f(x)=3X^2, then f'(x)=10x

If you mean as x →+∞, then the limit is +∞. Or rather, no limit. It is boundless.

In both cases their is no limit since the function becomes unboundedly large in the negative direction.
