Therefore the coordinates of the turning point are (-1, 2). If we recall the general equation: \(y = a{x^2} + bx + c\) then if: a > 0, then the shape of the parabola is like a happy face and the ...

c\). To get \(b\) (the number inside the bracket), halve the coefficient (number in front) of the second term in the original equation. Half of -6 is -3 so the bracket becomes \((x-3)\).

What are the underlying principles of how populations change over time? Two basic principles are involved, the idea of exponential growth and its ultimate control. The basics of population ecology ...
