Answer to: How to find a function from its derivative? By signing up, you'll get thousands of step-by-step solutions to your homework questions...
Another application is finding extreme values of a function, so the (local) minimum or maximum of a function. Since in the minimum the function is at it lowest point, the slope goes from negative to positive. Therefore, the derivative is equal to zero in the minimum and vice versa: it i...
Plugging in our difference quotient from Step 2 into our limit formula, we get thatf′(x)=limh→02=2. How to Find the Derivative of a Function Using the Limit of a Difference Quotient: Example 2 Find the first derivative off(x)=3x2+5x−2. ...

If x and y are otherwise independent, we represent the derivative along each axis in a vector: This is thegradient, a way to represent "From this point, if you travel in the x or y direction, here's how you'll change". We combined our 1-dimensional "points of view" to get ...
Here's my take on derivatives:We have a system to analyze, our function f The derivative f′ (aka dfdx) is the moment-by-moment behavior It turns out f is part of a bigger system (h=f+g) Using the behavior of the parts, can we figure out the behavior of the whole?

The derivative function (blue) crosses the x-axis where the original function (green) has a relative minimum. The above image demonstrates an important result of the fundamental theorem of algebra: a polynomial of degreenhas at mostnroots.Roots (or zeros of a function)are where the function ...
The derivative must exist for every point in the domain, otherwise the function is not differentiable. This might happen when you have a hole in the graph: if there’s a hole, there’s no slope (there’s a dropoff!). See:Differentiable vs. Non Differentiable Functions. ...
