Consider the function f() = 7(x -2)". For this function there are two important intervals: (-00, A) and (A, co) where A is a critical number. A is For each of the following intervals, tell whether f(@) is increasing or decreasing. (-00, A): Select an answer v (A, oo): Select an answer v For each of the following intervals, tell whether f(@ ) is concave up or concave down. (-00, A): Select an answer v (A, oo): Select an answer v
