Solution We can use the formula for the derivate of function that is the sum of functions f(x) = f 1 (x) f 2 (x), f 1 (x) = 10x, f 2 (x) = 4y for the function f 2 (x) = 4y, y is a constant because the argument of f 2 (x) is x so f' 2 (x) = (4y)' = 0 Therefore, the derivative function of f(x) is f'(xF(x)=\frac{1}{x^2} y=\frac{x}{x^26x8} f(x)=\sqrt{x3} f(x)=\cos(2x5) f(x)=\sin(3x) functionscalculator en Related Symbolab blog posts Functions A function basically relates an input to an output, there's an input, a relationship and an output For every inputFormula Difference quotient = (f (xh)f (x))/h In singlevariable calculus, difference quotient is used to compute the slope for the secant line (ie, the line passes between two points on a curve) between any two points in a graph for the function f
Aug 04, 16 · When working with a function, all you have to do is plug (x h) into your function wherever you see an x Let's look at the function f (x) = 2 x 6 To find our f (x h),Simply substituting x with xh doesn't do it, not to mention that the f's and the coefficients seem to have changed roles, with the f's now being functions instead of constants and the coefficients now being constants instead of functionsH f x −f x −h h f x h −f x −h 2h central difference formula threepoints formula Approximation error Consider the Taylor polynomials and remainder of f x h and f x −h ;
