Question

answer plzzz
partial derivative of f(x)=x^2+x+1 with respect to x.

Answer 1

partial? there is only one variable here

Answer 2

\[f(x)=x^2+x+1\]
\[f'(x)=2x+1\] that is all, since it is a function of only one variable

Answer 3

^ yep, partial derivative only applies if there's multiple variables and you're differentiating w.r.t. one of them.
