![Let f(x) = 8x- 9. Find the open intervals on which f is increasing (decreasing). Then, determine the a-coordinates of all relative
maxima (minima).

1.
f is increasing on the intervals
2.
f is decreasing on the intervals none
3. The relative maxima of f occur at x = none
4. The relative minima of f occur at x = none
Notes: In the first two, your answer should either be a single interval, such as (0,1), a comma separated list of intervals, such as (-inf, 2),
(3,4), or the word "none".
In the last two, your answer should be a comma separated list of x values or the word "none".
