This was solved earlier but I don't know how some of the steps happened. So I know how to get f(x) which should be 16. After that, I plug in the formula f(x)-f(a)/x-a which converts to 4x^3-3x-10-16/x-2. After that, I combined like terms and got 4x^3-3x-26/x-2. In class. We then factor the numerator, which isn't possible with this problem. The last person who solved this said f1(x)=4*3x^2-3(1)+0 but i don't understand how they separated 4x^3 to just 4 and 3x to 3x^2. Also don't know where that 1 or 0 came from.

8. Find the equation of the tangent line of the function at the given point. a.) f(x) = 4x3 - 3x - 10; a = 2
