Question

So here is a function f(x)=(x+4)/(x^2+5x+4)

We're supposed to find its
1.domain,range
2. limit at x approaches -4 and x approaches 1
3. Continuity at x=4 and x=-4
4. Rate of change at x=-4 x=-1 and x=2
5. Critical points
6. Increasing and decreasing intervals
7. Absolute Min and Max at x=-0.5 and x=5
8. Absolute Min and Max at x=-1 and x=5
9. Relative Min and Max
10. Inflection points and Continuity
