Power Rule for Derivatives. Example Problem 2 f(x)=x^3 -9x^2 -48x+5 f'(x)=0 f'(x)=3x^2 -18x-48=0 3(x^2 -6x-16)=0 3(x-8)(x+2)=0 x=8, -2 So. Now you need to find the values of x for which f(x) = x3 - 9x2 - 48x + 5 has a horizontal tangent. If we have a horizontal tangent, that means there's going to be a slope of 0-that is, f(x) = 0. That means the derivative of f(x) is equal to 0. We will find f prime of x,…...

The geometry of linear approximation A linear approximation of a function is a polynomial that passes through the sample points and has the same slope at each of them. The linear approximation of a function is often used in statistics; many statistical methods assume that the data are generated by some underlying model, and the linear approximation provides an alternative expression for the model's predictions. Let's go through it. So we take the x derivative of that. If we plug…...
