Answer:

Step-by-step explanation:
Quadratic Formula: 
√-1 is imaginary number i
Step 1: Define
y = -3x² + 4.5x - 20
a = -3
b = 4.5
c = -20
Step 2: Substitute and Evaluate







 
        
             
        
        
        
The mode of the following data values would be 21.
mode is usually a number that is repeated more than once, and in this case, 21 appears twice.
your answer is c
