Don’t know the answer nor the explanation ! Same situation as of yours !
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 :)
James runs 1 mile every 2 min. How many miles does he run every 3 mins?
The ratio of areas is the square of the scale factor, so that factor is
√(320/180) = 4/3
The answer is 7i because if you add 4+3i together as an absolute value, it equals to 7 plus the i is 7i
