LAST QUESTION PLEASE HELP ME

Answer 1

y = 3x^2 + 1/3

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

• x = 0
• y = 1/3

Solution

1/3 = a(0)^2 + c

1/3 = 0 + c

c = 1/3

Second Given

• x = - 3
• y = 82/3

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
