The diagram shows the graph of $$\(y=\mathrm{f}(x)\)$$ and the point $$\(P(-2,11)\)$$ ． The tangent from $$\(P\)$$ touches the graph of $$\(y=\mathrm{f}(x)\)$$ at the point $$\((a, b)\)$$ ． The values of $$\(a\)$$ and $$\(b\)$$ are integers． （a）By drawing this tangent，find the value of $$\(a\)$$ and the value of $$\(b\)$$ ． $$\[ a=\ldots \ldots \ldots \ldots \ldots \ldots \ldots, \quad b=\ldots \ldots \ldots \ldots \ldots \ldots \ldots . . \quad \text { [2] } \]$$
