Question: the problem is f(x)=2x^3 - 5/2^2 -21x+42 also a) says find and simplyfy f '(x) 15) Consider the function f(x) - 2x -2x -21x+42 a)

the problem is f(x)=2x^3 - 5/2^2 -21x+42 also a) says find

the problem is f(x)=2x^3 - 5/2^2 -21x+42

also a) says find and simplyfy f '(x)

and simplyfy f '(x) 15) Consider the function f(x) - 2x -2x

15) Consider the function f(x) - 2x -2x -21x+42 a) Find and simplify f (x) b) Find an equation of the tangent line to the graph when x = 2 c) For what x values, does the function have horizontal tangent lines? Show work
