2 log(x) - x
log(x) - x^2
Differentiate −x2+log(x)- x^{2} + \log{\left(x \right)}−x2+log(x) term by term:
The derivative of log(x)\log{\left(x \right)}log(x) is 1x\frac{1}{x}x1.
The derivative of a constant times a function is the constant times the derivative of the function.
Apply the power rule: x2x^{2}x2 goes to 2x2 x2x
So, the result is: −2x- 2 x−2x
The result is: −2x+1x- 2 x + \frac{1}{x}−2x+x1
The answer is:
1 - - 2*x x
/ 1 \ -|2 + --| | 2| \ x /
2 -- 3 x
