# Is f(x)=-x/e^(x^2-3x+2) increasing or decreasing at x=4 ?
Jun 11, 2017
$f$ is increasing at $x = 4$
#### Explanation:
Since the derivative of a function $f$, denoted $f '$, is the "instantaneous rate of change" of the function. A way to tell the behavior of a function around a point is to take the derivative. If... | {} |
# Integration of (ax+b)/(cx+d)
The integration of (ax+b)/(cx+d) is equal to ax/c + (bc-ad)/c2 ln|cx+d|+K where K is an integral constant and ln denotes the natural logarithm. In this post, we will learn how to integrate the function (ax+b)/(cx+d).
