A car travels a distance described by $d(t) = 4t^2 + 2t$ km in hours. Find the average speed from $t = 1$ to $t = 3$.
💡 Hint: Use the AROC formula on distance.
Given the function $g(x) = x^3 - 3x^2 + 4$, calculate the IROC at $x = 1$ and interpret its significance.
💡 Hint: Differentiate $g(x)$ then evaluate at $x = 1$.
