Given that y is positively proportional to the square + 1 of X, and x = - 3, y = 20, then the function relation is
The solution is proportional to the square of Y and X + 1
Let y = K (x ^ 2 + 1)
When x = - 3, y = 20
That is, K ((- 3) ^ 2 + 1) = 20
That is, 10K = 20
The solution is k = 2
So the function relation is y = 2x ^ 2 + 2
