## Study Notes

### Derivative of a Function

• The derivative of f(x) = 3x^2 + 2x - 5 with respect to x represents the rate of change of the function.

### Rational Root Theorem

• The rational root theorem is used to find possible rational roots of a polynomial equation.
• In the equation 2x^3 - 4x^2 + 3x - 4 = 0, the rational root theorem is used to find the possible rational roots.

### Electric Field Intensity and Electric Potential

• Electric field intensity and electric potential are related, with electric field intensity being the negative gradient of electric potential.
