WebThe slope formula is: f (x+Δx) − f (x) Δx. Put in f (x+Δx) and f (x): x2 + 2x Δx + (Δx)2 − x2 Δx. Simplify (x 2 and −x 2 cancel): 2x Δx + (Δx)2 Δx. Simplify more (divide through by Δx): = 2x + Δx. Then, as Δx heads towards 0 we get: = 2x. Result: the derivative of x2 is 2x. In other words, the slope at x is 2x. WebThis is valid by the fundamental theorem of calculus.
