Question
Answer:
First what we must do is rewrite the table to find a solution:
 0.25^x −0.75x+1
    64     3.25 
    16     2.5 
     4      1.75 
     1      1
  0.25     0.25 
  0.0625 −0.5   
  0.015625  −1.25 
 We see where the values of the function are the same:
 x = 0 (1)
 x = 1 (0.25)
 answer:
 x = 0
 x = 1
