4 If the second derivative f '' is negative () , then the function f is concave down ( ) 5 The point x = a determines a relative maximum for function f if f is continuous at x = a , and the first derivative f ' is positive () for x < a and negative () for x > a The point x = a determines an absolute maximum for function f if itIf y = xsqrt(1 x^2) then y^2 = x^2(1 x^2) = x^2 x^4 Now differentiate implicitly 2ydy = (2x 4x^3)dx, therefore, cancel 2s and x and make dy/dx the subject of the formula ydy = (x 2x^3)dx = x(1 2x^2)dx => dy/dx = x(1 2x^2)/y => dy/Jonbenedick shared this question 7 years ago Answered How can you graph the derivative of y=x!?

Given a function , there are many ways to denote the derivative of with respect to The most common ways are and When a derivative is taken times, the notation or is used These are called higherorder derivatives Note for secondorder derivatives, the notation is often used At a point , the derivative is defined to be It means the slope is the same as the function value (the y value) for all points on the graph Example Let's take the example when x = 2 At this point, the y value is e 2 ≈ 739 Since the derivative of e x is e x, then the slope of the tangent line at x = 2 is also e 2 ≈ 739 x = 2 \displaystyle {x}= {2} x= 2453 Use concavity and inflection points to explain how the sign of the second derivative affects the shape of a function's graph 454 Explain the concavity test for a function over an open interval 455 Explain the relationship between a function and its first and second derivatives 456 State the second derivative test for local extrema

Definition Derivative Function Let f be a function The derivative function, denoted by f ′, is the function whose domain consists of those values of x such that the following limit exists f ′ (x) = lim h → 0f(x h) − f(x) h A function f(x) is said to be differentiable at a if f ′ (a) exists If you do a simple test visually say, the first segment of your reference graph is concave up and positive slope The positive slope notifies that the graph of the derivative will be in the positive terminal The concave up quality of the initial part of the graph assumes that the derivative is increasing The value of is the derivative of y with respect to x, but in this context it is also called the slope of the tangent line So, the derivative of a function at a certain point is the slope of the tangent line that point If we zoom back out again, eventually the graph of no longer looks like a line;

The graphs of a function and its inverse are mirror images across the line y = x If (x, y) is on f(x), then (y, x) is its mirrorimage point across y = x, and the slope of f(x) at x is the reciprocal of the slope of f1 (x) at yGet stepbystep solutions from expert tutors as fast as 1530 minutes Your first 5 questions are on us!To find the equation of the tangent line, we need a point and a slope at that point To find the point, compute f(π 4) = cotπ 4 = 1 Thus the tangent line passes through the point (π 4, 1) Next, find the slope by finding the derivative of f(x) = cotx and evaluating it
