What is the range of the function y = -x2 + 1?
1 answer:
To solve this problem you must apply the proccedure shown below:
1- You have the following function given in the problem above:
y=-x²<span> + 1
</span>
2- If you graph the function, you will obtain the parabola shown in the figure attached. As you can see, the vertex is ( the maximum value of y is y coordinate of the vertex is (0,1) and the parabola opens down. Therefore the range is:
Range: {y∈R:y≤1}
Therefore, the answer is: {y∈R:y≤1}

Answer:
A. $ 24 7/8
Step-by-step explanation:
GIVEN: A stock starts the day at $27 3/8 per share.
Share drops $2 1/2 during the day.
To Find : Closing value
Solution : first we need to find how many 1/8 are there in 1/2
So,
when share drops by $2 then share will be :
$27 - $2 =$25
and
⇒
⇒
So,
⇒
So, its closing value is .
