Challenge 1 Hard

A cyclist travels along a path defined by the function h(t) = -4t^2 + 20t + 1. Calculate the average rate of change from t = 2 to t = 4, and then find the instantaneous rate of change at t = 3.

💡 Hint: Remember the formulas for AROC and IROC, and evaluate accordingly!

Challenge 2 Hard

A function g(x) models the profit of a company: g(x) = 5x^2 - 10x + 15. Determine the average rate of change between x = 1 and x = 5, and explain what it indicates about the company’s profit behavior.

💡 Hint: Calculate the function values first!
