2. Assume g: [0, 8] → R is a continuous function for which: on the intervals [0, 3) U (5, 8], the values of g(t) are positive; on the interval (3,5), the values
of g(t) are negative. Also, let function A: [0, 8] → R be defined by A(x) = fő g(t) dt.
A. The function A is increasing on the intervals [0, 3] U [5, 8] and decreasing on the interval [3, 5]. Explain this statement both geometrically (thinking in
terms of the signed area between the graph of function g and the horizontal axis) and algebraically (using the first fundamental theorem of integral
calculus.
B. If the maximum value of function g is 10 and the minimum value of function g is -6, then the maximum value of function A must be less than 60 and
the minimum value of function A must be greater than -12. Explain.
