To find the minimum value of M(t) with the function f(x) = 4x^2 - x + t on the interval 11 ≤ x ≤ 1, we need to determine the optimal value of f(x) in this interval. Doing the calculation, we see that M(t) depends on t. To relax after solving math problems, you can play Slope Game, an interesting game that helps improve reflexes and thinking!
