The equation of a curve is $$\(y=2 x^{2}-3\)$$. Two points $$\(A\)$$ and $$\(B\)$$ with $$\(x\)$$-coordinates 2 and $$\((2+h)\)$$ respectively lie on the curve. Explain how the gradient of the curve at the point $$\(A\)$$ can be deduced from the answer to part (a), and state the value of this gradient. ........................................................................................................................................................ . ........................................................................................................................................................ . ........................................................................................................................................................ . ........................................................................................................................................................ . ........................................................................................................................................................ . ........................................................................................................................................................ . ........................................................................................................................................................ . ........................................................................................................................................................ . ........................................................................................................................................................ . ........................................................................................................................................................ . ........................................................................................................................................................ .
