## Calculus
1. Suppose we have $\sigma (x)=\dfrac{1}{1+e^{-x}}$, find $\dfrac{d\sigma (x)}{dx}$.
($A$) $\sigma(x)^2$ *($B$) $\sigma(x)(1-\sigma(x))$ ($C$) $(1-\sigma(x))^2$ ($D$) $\dfrac{1}{1-\sigma(x)}$ ($E$) None of above
2. Find the $x$-coordinates for local minimum and local maximum of $f(x)=x^5-6x^3-8x+4$.
($A$) Doesn't have one ($B$) $(2,-2,1,-1)$ ($C$) $

## Calculus
1. Let the function $f(x)=ax^3+bx^2+cx+d$. Suppose that $f(0)=4$ is a critical point of $f$ and $f(1)=-2$ is a point of inflection, find $a$, $b$, $c$ and $d$.
Hint: The critical point of $f$ is the point such that $f'(x)=0$, and the point of inflection of $f$ satify $f''(x)=0$.
($A$) $a=1$, $b=5$, $c=8$, $d=6$
($B$) $
