Question

What is the derivative of 2x^2-x^4?

Answer 1

Multiply the exponent of each term by it's coefficient. Then subtract the exponent by one.

Answer 2

Yes, so I got 4x-4...but I am pretty sure it is not a four. ..

Answer 3

Yeah, you are wrong.

Answer 4

I'm really stuck. Would it be a 1?

Answer 5

2x^2, you would do bring down the two, so yes, 4x. The other one would be -x^4, bring down the 4, multiply it by -x and subtract the exponent by one.

Answer 6

No.

Read what I wrote, if you don't get it, I'll tell you regardless.
