problem 5. a) state the Definition of the Derivative via Limit for y = Flx ). (16 points ) CA ) b ) Find the Derivative of y = fix) where P ( x ) = - 3X + 2 x + 4 using b) only the Definition of The Derivative as inpart (a) Then, verify it using Rules of Differentiation ( ) True or False ? why? IF a Function is Continuous atx= a, then it is Differentiable atx= a. ( ) d ) suppose P ( x)= 5X - 3. Find the Marginal profit at X = Bunts and 3 x 2 + 1 state what it predicts about the sale of the next unit of ) ( page 6 )
