Let \(A(t) = 3- 2t^2 + 4^t\). Find \(A(2) - A(1)\).
Find all values of \(s\) such that \((s + 4)(s - 3) \le 0\). Give your answer as an interval.
Find all values of \(t\) such that \(8t^2 \le 3-10t\). Give your answer in interval notation.
PS: sorry about problem 2, my image files were glitching so I had to put it as a link
