We have that
<span>the equation 
y=-3x</span>²<span> + x -4
the </span><span>real number solutions are the points x intercept of the graph
are the points when y=0
using a graph tool
see the attached figure
</span><span>the graph has no point of intersection with the x axis
</span>therefore
the answer is
there are zero real numbers solutions
 
        
        
        
Answer:
1.25E16
Step-by-step explanation: calculator 
 
        
             
        
        
        
<span>f(x)= x³-x²-9x+9 has x², so it will be 
many to one function ( one value of y will correspond several values of x).
Answer is B.</span>
