Let f(x) be defined such that f(2) = 3 andf'(x) = cos(1/x + x) where 1 f '(x) = cose + x), x2 where 1

Let f(x) be defined such that f(2) = 3 andf'(x) = cos(1/x² + x) where 1

f '(x) = cose + x), x2 where 1 < x < 4. Let f(x) be defined such that f(2) = 3 and Part A: Find the tangent line approximation for f(2.1). (25 points) Part B: If f(2.1) has an actual value of 2.12, use the shape of the graph to determine if this is an overestimate or underestimate. Justify your answer. (15 points)
