Answer:

Step-by-step explanation:
Quadratic function is given as 
Let's find a, b and c:
Substituting (0, 6):



Now that we know the value of c, let's derive 2 system of equations we would use to solve for a and b simultaneously as follows.
Substituting (2, 16), and c = 6








 => (Equation 1)
 => (Equation 1)
Substituting (3, 33), and c = 6








 => (Equation 2)
 => (Equation 2)
Subtract equation 1 from equation 2 to solve simultaneously for a and b.

 
 
 
Replace a with 4 in equation 2.
 
 
 
 
 
 
 
 
 
 
The quadratic function that represents the given 3 points would be as follows:



 
        
             
        
        
        
Answer:
x = 1
Step-by-step explanation:
Add 4 from both sides which you add to the zero. Then, combine like terms, 5x - 1x which is 4x. Divide 4 from both sides and it equals 1.
