Consider the function f(x) = 7x – 6x? – 2. Identify the locations where f has transition points, the intervals of increase, decrease, and the intervals where f is concave up and concave down. (For any interval, give your answers as intervals in the form (*, *). Use the symbol co for infinity, U for combining intervals, and an appropriate type of parentheses "(",")", "[", or "]" depending on whether the interval is open or closed. Express numbers in exact form. Use symbolic notation and fractions where needed. Enter DNE if no such interval exists. When identifying the location(s) of the transition point(s), if multiple points exist, separate each x-value with a comma and enter DNE if no such x-value exists.)
