Answer:
B
Step-by-step explanation:
domain is the set of x-values
range is the set of y-values (corresponding to the x-values)
Now, since we want the range, we can immediately eliminate Choices C & D because they dealing with the DOMAIN ONLY (since x values).
Now, we have to choose from option A or option B.
The only difference is the greater than or less than sign with "equal to" signs as well. Whenever we are given 2 coordinate points, we can say that ALWAYS, we can graph a line segment using these 2 points. And line segments are all SOLID {meaning that the endpoints are INCLUDED).
What we mean by included is that the inequality sign should have "equal to" with it. Also, the two values of y-values are 3 and 5, thus range would be between 3 and 5 (inclusive). We can write:
Range = 3 ≤ y ≤ 5
Correct choice is B
A function is a relationship between inputs and outputs, such that an input is mappable to one output only
The height of the rocket 1 second after launch is <u>104 feet</u>
The reason the height value above is correct is as follows
The given equation for the height of the rocket is presented as follows;
h(t) = -16·t² + 48·t + 72
Where;
h = The height of the rocket above ground in feet
t = The time in seconds
The given function gives the height of the rocket above ground in feet <em>t</em> seconds after the rocket is launched
Height of the rocket 1 seconds after launch is h(1) = -16×1² + 48×1 + 72 = 104
Therefore, the height of the rocket 1 second after launch, h(1) = <u>104 feet</u>

Answer: 
.
Step-by-step explanation:
We know that the slope of a line passing through points (a,b) and (c,d) is given by :_
The given points : (-4,3) and (-2, -4)
Now, the slope of the line passing through points (-4,3) and (-2, -4) is given by :-
The slope of a line passing through points (-4,3) and (-2, -4) is .
