SUMMARY

The discussion focuses on sketching the graph of a differentiable function f with the conditions f(2)=0, f' < 0 for x < 2, and f' > 0 for x > 2. Participants noted that a parabola is a suitable representation of such a function, while also considering the absolute value function as a potential candidate. The consensus is that the absolute value function is differentiable except at the point where x equals 2, aligning with the requirements of the problem.

PREREQUISITES
  • Understanding of differentiable functions
  • Knowledge of calculus concepts such as derivatives
  • Familiarity with graph sketching techniques
  • Basic properties of absolute value functions
NEXT STEPS
  • Study the properties of differentiable functions in calculus
  • Learn about the implications of derivative signs on function behavior
  • Explore graphing techniques for polynomial and absolute value functions
  • Investigate points of non-differentiability in piecewise functions
USEFUL FOR

Students studying calculus, mathematics educators, and anyone interested in understanding the behavior of differentiable functions and their graphical representations.

Homework Statement


Sketch the graph of a differentiable function f such that f(2)=0, f' < 0 for -infinity < x < 2, and
f' > 0 for 2 < x < infinity.



Homework Equations





The Attempt at a Solution


I have answered this question correctly, but what interested me was that in the back of the book it said that individual answers may vary. When I answered this, I immediately thought of a parabola, but I was wondering if an absolute value function would work as well.

Is abs differentiable?
 
I would say yes, just when x doesn't equal 2.
