Answer:
the function is either increasing or decreasing
Step-by-step explanation:
For m ≠ 0, the function must be either increasing or decreasing. If the function is increasing, it will have its maximum value at the right end of the interval. If it is decreasing, its maximum value will be at the left end of the interval.
-30, -31, -32
-30 + -31 + -32 = -93
Step-by-step explanation:
If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence.
d=-7+3=-3-1=1-5=-4
so it is an arithmetic sequence
