find the gradient of the curve y=3x^4-2x²+5x-2 at the points (0,-2) and (1,4)

do i just differentiate once? its been years since ive done this, any help? cheers

But, again, why is this calculus problem posted under "Number Theory"?

The term "gradient" is normally used for a function of at least two variables. For the single-variable case, we use "slope".

I wasn't aware of that. I'm actually surprised.

Thanks!!
