- (a) The function is increasing on the interval (0, infinity)
- (b) The function is decreasing on the interval (-infinity, 0)
=======================================================
Explanation:
You should find that the derivative is entirely negative whenever x < 0. This suggests that the function f(x) is decreasing on this interval. So that takes care of part (b).
The interval x < 0 is the same as -infinity < x < 0 which then translates to the interval notation (-infinity, 0)
Similarly, you should find that the derivative is positive when x > 0. So the function is increasing on the interval (0, infinity)
Answer:
"You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function!"

Answer:
Step-by-step explanation:
1) q=90/180=45/90=...=1/2;
2) the formula of the n-th term of the given sequence is:
3) according to the formula 15th term is:
or ≈0.011.
Answer:
Is a relation and a function.
Step-by-step explanation:
Every set of order pairs represent a relation.
Remember that a relation is a function when every element from the domain has a unique corresponding element in the range. In this case
f(-2) = 3
f(2) = 7
f(7) = -12
f(10) = -15
Therefore the relation is a function as well.
