PART A: Sketching DerivativesExercise 1: For each graph below…A) Use the graph to sketch the graph of the derivative.
ChallengeA) Try to determine an equation of the original curveB) Determine an equation of the derivative.C) Use technology to graph the derivative and verify your original sketch from A).(Each tick represents one unit, except in v) where xticks = π, yticks = 2)

Exercise 2: 1. Sketch a function that has all of the following properties.a) f(x) is a smooth, continuous and odd function defined everywhereb) f(1) = 0.5, f/(1) = 0, f//(1) > 0c) f//(x) > 0, when 0 < x < , f//(x) < 0, when x >d)
2. Determine an equation for the function above and verify the information provided.
