X = 4, -9
x^2+5x-36=0
1x +5x-36=0
1x (-1x) + 5x (- -1x) -36 = 0
4x - 36 = 0
4 x - 36( - - 36) = 0
4x = -36
4x/4 = -36/4
x= -9
The midpoint of the range of frequencies given is:
midpoint = (82.4 +
659.2) / 2 = 370.8 Hertz
Then the difference from midpoint to the other end is:
370.8 - 83.4 = 288.4 Hertz
Therefore the inequality formula is
|f - 370.8| <= 288.4
Tough call.
You may have to use Newton's Method or something like that.
Graph y=2^x and then graph n/x on the same set of axes. You may have to assign some arbitrary value to n to make this work. From the graph you can read off the approximate coordinates of the point of intersection.
