Best ResponseYou've already chosen the best response.1Just remember this, and maybe you'll be able to see how a lot of the problems are very similar in nature, just worded differently: The derivative a function, f(x), is a function to find the slope of the tangent line at any x value. The slope of the tangent line is the instantaneous rate of change for the original function, f(x). Whenever the question asks anything about the tangent line of a function, the first step is almost always to differentiate. Just in case, in any opening calculus class, differentiate first, and then work from there. Just try to remember what the derivative a function actually is. Don't just memorize how to use it.
