2. What's the equation of the line that's tangent to f(x) = 3x - 8x at x = 2? 3. Draw a graph below that satisfies all of these 4 properties: f(-2) = 4, f(2) = 2 f ' ( - 2 ) = 2 , f ' ( 2 ) = 4 4. Recall the formal definition of the derivative, which is given below: f' ( x) = [(xth)-f(x) a) Using this definition, calculate the derivative of f(x) = x + 2. You must show work. b) Graphically, what does h represent in this process and why are we considering h values getting close to zero
