To find the derivative of x2, we use the power rule for differentiation, which states that dxd(xn)=nxn−1.
Step 1: Identify the function and the exponent.
The function is f(x)=x2.
The exponent is n=2.
Step 2: Apply the power rule.
dxd(xn)=nxn−1
Substitute n=2:
dxd(x2)=2x2−1
Step 3: Simplify the expression.
dxd(x2)=2x1
dxd(x2)=2x
The derivative of x2 is 2x.
