WebAnswer is 6x Explanation: The thing with differentiating is that it is so easy if you know how to do it. An equation like a polynomial is easy since if there is an exponent and you ... WebSo it's gonna be that over 1, plus the square root. One plus the square root of x squared minus one. So this is a composition f of g of x, you get this thing. This is g of f of x, …

WebHow do you find the slope of the secant lines of f (x) = 7x2 at (4, f (4)) and (4 + h, f (4 + h))? How do you find the slope of the secant lines of f (x) = x2 + 5x at (6 , f (6)) and (6 + h , f (6 + h))? How do you find the slope of the secant lines of f (x) = x2 − x − 42 at (−5, −12), and (7, 0)? What is the slope of y = 4x − 3 at x = − 1? WebAug 29, 2015 · The limit doesn't care what happens when x is equal to 1, it wants to onow what happens when x is close to 1, so we get: lim x→1 3(x +1)(x −1) x − 1 = lim x→1 3(x +1) = 6 The slope of the tangent we were asked about is 6. Short method For f (x) = 3x2, we get f '(x) = 3 ⋅ 2x2−1 = 6x The slope of the tangent at 1 is f '(1) = 6(1) = 6 Answer link dew electronics

WebDifference Quotient Formula: The difference quotient equation measures the approximated form of derivative as: $$ f (x) = f (x + h) – f (x) / h $$ Where “h” is the step size and f (m) is a function. This computes the rate of change of given function f (x) over the interval [x, x + h]. How to Find Difference Quotients? WebIf f (x) = 4 - x2 and g (x) = 6x, which expression is equivalent to (g - f) (3)?
