Question

2) Assume that a 20mm by 20mm section of tissue was placed on top of a Cartesian plane with its center at the origin. The darker, shaded areas found on the tissue sample satisfy the rational inequality 1/x²-9 > 0. Sketch a graph of the function f(x)= 1/x²-9 by hand and shade the region(s) of the graph that satisfy the inequality to reveal the light and dark regions of the biopsy noted by Dr. Yen. ​

Answer 1

The darker, shaded areas found on the tissue sample satisfy x+1 the rational inequality ->0. x2 -9 a) Sketch a graph of the function 1+1 f(x)= by hand. .1-9 b)
