A car's position is given by the function s(t) = t^4 - 8t^3 + 18t^2. Find the acceleration of the car and determine if the car is speeding up or slowing down at t=2.
💡 Hint: Remember to evaluate the signs of both derivatives at t=2.
Find and classify all critical points of the function f(x) = x^4 - 4x^3. Indicate if they are local maxima, minima, or points of inflection.
💡 Hint: Evaluate both f' and f'' around the critical points.
