Answer:
y = 5x^2+10x +14
Step-by-step explanation:
y = 5(x+1)^2+9 
= 5(x^2+2x+1)+9
= 5x^2+10x +14
 
        
             
        
        
        
The common difference is 4. U know that the formula is the first term + d(n -1). N-1 is 14 so u know that 14 times a number needs to equal 56 because the first term is -3 and 56-3 is 53. 14 * 4 is 56. So the common difference is 4
