Derivative of x Squared
2/8
What is the derivative of f(x) = x²?
A
2, since the exponent of x² is 2 and the derivative extracts that constant
B
x, since differentiation reduces the polynomial degree by one without scaling
C
x², since squaring is its own derivative for polynomial functions
D
2x, since the power rule gives d/dx(xⁿ) = nxⁿ⁻¹
