Answer:
B. -6 does not belong to the domain but belongs to the range of f(x).
Step-by-step explanation:
We have the function, .
So, the domain of the function is obtained when i.e.
That is, the domain is {x | x≥ 7}.
Now as we have,
→ → → → .
That is,
Thus, the range of the function f(x) is {y | y≤ 1}.
Thus, we can see that,
-6 does not belong to the domain but belongs to the range of f(x).
I don’t think it’s right, but I got $0.02
Answer:
(D) 400
Step-by-step explanation:
It is given that The distance from Earth to the moon is 2.39 × 105 miles, and the distance from Earth to Mercury is 9.2 × 107 miles. Then,
Distance from Earth to Mercury compared to the distance from Earth to the moon is given by:
=
=
≈400.
therefore, option D is correct.
Answer:
B
Step-by-step explanation:
There is no change in cost, so the slope stays the same. since the a dependent variable is cost, it stays on the y axis, and the amount of photocopies is on the x axis. The total amount of money for 8 copies is $1.60, so you would just plug those into the graph and find B to be correct.
