1) (1 points) Start with the tangent line approximation of f(x) at (x0, y0), y y0 = m(x x0) to derive the formula for the Linearization of f(x) at x = a. Hint: Let x0 = a and y0 = f(a). The tangent line approximation, or equivalently the Linearization L(x), is the best first-degree (linear) approximation of f(x) near x = a because f(a) = L(a) and f(x) and L(x) have the same rate of change (derivative) at a.
