Best ResponseYou've already chosen the best response.0For f(x+h), replace all x by x+h in 4x^3 3x+1. For f(x), it's just 4x^3 3x+1. \[ \frac{f(x+h)f(x)}{h} = \frac{(4(x+h)^3 3(x+h)+1)  (4x^3 3x+1)}{h} =...\]

Best ResponseYou've already chosen the best response.0Since this is how you get the derivative for small h, you should find answer close to 12x^2  3.

Best ResponseYou've already chosen the best response.0okay I wrote the wrong equation b4, but I just corrected it. What is the next step after I write out: (4(x+h)^2 3(x+h)+1)(4x^2 3x+1)/h)
