Answer:
y = 3x^2 + 1/3
Step-by-step explanation:
The first step is the easiest. Find the value of c. That means that all you are left with is c and y because x and a disappear when x = 0.
y = ax^2 + c
Givens
Solution
1/3 = a(0)^2 + c
1/3 = 0 + c
c = 1/3
Second Given
Second Solution
82/3 = a*(-3)^2 + 1/3 Subtract 1/3 from both sides
82/3 - 1/3 = a*(9) + 1/3 - 1/3
81/3 = 9a Reduce the left
27 = 9a Divide by 9
27/9 = a
3 = a
Answer
y = 3x^2 + 1/3
