Answer:
a) at x=0.5 y=2 and at x=1 y=2 this similarity in values shows that the solution for x is between 0.5 and 1
c) The x solution will be between x=0.0 and x=0.7 .
There is a similarity in values of y at x=0.6, y=2.4 and at x=0.7 , y=2.4
d) For x= (0.6+0.7)/2 = 1.3/2 =0.65
For y= (2.4+2.3)/2 =4.7/2=2.35
Approximate solution is (0.65, 2.35)
