Unless you are asked to use the limit definition of the derivative, why not just use the rules/properties?
Part I
a.) find the slope of the tangent lineto the graph of the function f at point . b.) Find the points on the graph where the tangent line is horizontal and use these points to sketch the graph.
Part II
Find the indicated derivative:
Hey can you use the
to solve the formula? coz i can really get it there
Part III
Find
