Answer
Given the parabola with x-intercepts at -6 and 1, the factored form of the equation is \(y = a(x - 1)(x + 6)\). To find the value of 'a', we can use the point (2, -2) which the parabola passes through.Plugging the coordinates of the point into the equation, we get:\(-2 = a(2 - 1)(2 + 6)\)\(-2 = a(1)(8)\)
Now, solve for 'a':
So, the value of 'a' is
