Question

Find dy/ dx of the function y = x 2 using the definition of derivative.​

Answer 1

Answer:

Derivatives as dy/dx

Add Δx. When x increases by Δx, then y increases by Δy : y + Δy = f(x + Δx)

Subtract the Two Formulas. From: y + Δy = f(x + Δx) Subtract: y = f(x) To Get: y + Δy − y = f(x + Δx) − f(x) Simplify: Δy = f(x + Δx) − f(x)

Rate of Change.
