Answer: D.The domain and range of the function are the same.
Step-by-step explanation: Given function f(x)=-√-x.
The given function is a square root function and we have minus sign in front of x inside square root.
A square root always defined for positive values or 0.
In order to get a positive number or 0 inside square root, let us solve the inequality:
On dividing both sides by -1, the inequality sign would get flip and we get
<h3>Domain:
</h3>
We can see that we have a negative sign in front of square root. So, the value of f(x) would be always a negative number or 0.
<h3>Therefore, range would also be :
.</h3><h3>Therefore, correct option is D option.</h3>
Answer:
to the tenths place, 32.86
Step-by-step explanation: It is because money is always rounded to the tenths place
31 = -4v - 5
31 (+5) = -4v -5 (+5)
36 = -4v
36/(-4) = -4v/(-4)
36/ -4 = v
v = -9 is your answer
hope this helps
Can you tell us the question?
Answer:
1000
Step-by-step explanation:
To find the value of a digit in a number, set all the other digits to zero.
The value of 7 in 7042 is 7000.
The value of 7 in 427 is 007 = 7.
Then the question is "how many times larger is 7000 than 7?" That result is found by dividing 7000 by 7:
7000/7 = 1000
The 7 in 7042 is 1000 times larger than the 7 in 427.
_____
<em>Another way to consider this</em>
The 7 in 7042 is in the "thousands" place. The 7 in 427 is in the "ones" place. The thousands place is 3 places to the left of the ones place. Each place moved to the left increases the value by a factor of 10, so the value of a digit in the thousands place is 10×10×10 = 1000 times that of the same digit in the ones place.
