Use the graph of f to find [math] so that [math] when [math] if [math] and [math].
To change the graph enter values for

x min = x max=

y min = y max=
and then press the Submit Answer button.

Note: [math] and [math] are graphed in red to help you find [math]. Mathematically speaking, once you have found [math] any smaller number will also work for [math]. Since that would make the problem rather easy, you could just put in a very small number, for this problem you will need to find the largest delta that will work. Your answer must be within 3e-06 of the correct answer.
