Question 1. (5 points) Let f(x) = 2x2 + 5x. Use the definition of the derivative to find f'(2) and then use your answer to find an equation of the tangent line to the graph of f at the point (2, f(2)). Question 2. (5 points) Use the definition of the derivative to find f'(x) where f(x) = v2x + 1. Then state the domain of f and the domain of f
