Start by taking the derivative. This will require product rule and chain rule. The product rule is: AB'+BA' `f'(x) = (x2)(2x) + (x^2+4)(1)` `f'(x)= (x2)(2x) + x^2+4` `f'(x)= 2x^2 4x+x^2+4` The...

Take the derivative for the derivative function. `f'(x)= 21/5 x^2` Substitute the point where x=0 to find the slope at that point. `f'(x)= 21/5 (0)^2= 0` The slope at that point is zero....

Take the derivative of the function. `y' = sqrt3 2sin(x)` Set the derivative function equal to zero, since we want to know where x is when the slope is zero. `0 = sqrt3 2sin(x)` `2sin(x)=sqrt3`...

Eliminate the radical by rewriting it as a fraction. The function becomes: `f(x) = 2/ (x^3)^(1/4) = 2/x^(3/4) = 2x^(3/4)` Take the derivative by using the power rule. `f'(x) = 3/4...
