Answer:
   3 3/4
Step-by-step explanation:
   
__
The integer part of the mixed number is the quotient when the numerator is divided by the denominator. The remainder from that division is the numerator of the fraction.
   15/4 = 15 ÷ 4 = 3 r 3 = 3 3/4
 
        
             
        
        
        
Replace each of the x values given to see if they give 0. 
0=(2/3)³+(2/3)²-1 
0=(8/27)+(4/9)-1 
0≠-0.259
0=(1)³+(1)²-1 
0≠1
Therefore, you can see that the solution would have to be between 2/3 and 1.
Hope I helped :)
