What is f(–2) quizlet
What is f(–2) quizlet-Now that we have explored derivatives, we can begin to assess what f' and f'' say about f You may already have recognized some properties of first and second derivatives, but here we will lay them all out The following statements are true a) If f'(x) >0 on an interval, then f is increasing on that intervalThat we know an interval a,b on which f(x) changes sign If f(x) is actually a continuous mathematical function, then there must be a point x∗ somewhere in the interval where f(x∗) = 0 But the notion of continuity does not strictly apply to floatingpoint computation We might not be able to actually find a point where f(x) is exactly

For each of the following functions, verify that the function satisfies the criteria stated in Rolle's theorem and find all values \(c\) in the given interval where \(f'(c)=0\) \(f(x)=x^22x\) over \(−2,0\) \(f(x)=x^3−4x\) over \(−2,2\) Solution Since \(f\) is a polynomial, it is continuous and differentiable everywhereThe function f is evaluated for the value of c if f(c) = 0 means that we found the root of the function, which is c6041/6431 Spring 08 Quiz 2 Wednesday, April 16, 730 930 PM SOLUTIONS Name Recitation Instructor TA Question Part
On the graph of a line, the slope is a constant The tangent line is just the line itself So f' would just be a horizontal line For instance, if f (x) = 5x 1, then the slope is just 5 everywhere, so f' (x) = 5 Then f'' (x) is the slope of a horizontal linewhich is 0 So f'' (x) = 0 See if you can guess what the third derivative is, or1/2 1/2 t f (t) = rect(t) If x(t) ,X(f), then X(t) ,x(f) In other words, FFx(t) = x(t) The Fourier transform of a sine or cosine at a frequency f 0 only has energy exactly at f 0, which is what we would expect Cu (Lecture 7)0 where x is the number Note that average velocity is found over a time interval Instantaneous velocity is usually called velocity, and it can be found at any time x, as follows We can, of course, use variables other than x and y to represent functions and their derivatives

While some functions are increasing (or decreasing) over their entire domain, many others are not A value of the input where a function changes from increasing to decreasing (as we go from left to right, that is, as the input variable increases) is called a local maximumIf a function has more than one, we say it has local maximaCorrect answers 2 🔴 question What is the average rate of change for the function f(x) = x^27x4 over the interval (0,2)The theorem implies that there is at least one x 0 x_0 x 0 such that f (x 0) = y 0, f(x_0) = y_0, f (x 0 ) = y 0 , but there may be more than one, depending on f f f and y 0 y_0 y 0
