Help me with this * 1 (1 point) Use linear approximation, i.e. the tangent line, to approximate 99* as follows: Let f(x) = x'. The equation of the tangent line to f(x) at a = 102 is best written in the form y = f(a) + f'(a) . (x - a) where a = , f(a) = and f'(a) = Using this, we find our approximation: 99
