Hello from MrBillDoesMath!
Answer:
Domain = { 5. 10. 15. 20}
Range = -3,-1,1,3}
.
Discussion:
The domain is the set of all "x" values, that is { 5. 10. 15. 20} and the range is (-3,-1,1,3}
. The arrows in the diagram show the mapping between the domain and the range. For examples, 5 -> 1 ( "x value 5 is mapped to y value 1"), 10 ->3, 15 ->-3, and 20 -> -2
Thank you,
MrB
743 is a prime number because it has no other positive divisors besides one and itself.
Answer:
A. The function is always decreasing
Step-by-step explanation:
we read a graph from left to right, so we can always compare the increase/decrease of a function by seeing how an x value compares with an x value to the left
(I am aware that this paragraph is really confusing)
we can see that as x increases, from -∞ to 0,
y decreases in correspondence
and that as x increases, from 0 to ∞,
y decreases in correspondence also
So, even though the graph doesn't quite look like it, when x < 0; the function decreases, when x > 0; function decreases--so the function is always decreasing
hope this helps!! have a lovely day :)
