Answer:
Option D. 
Step-by-step explanation:
we know that
If air resistance is ignored, the height h (in feet) of the ball t seconds after it is served is given by
where
g is the acceleration due to gravity which on earth is approximately equal to 32 feet / sec^2
V_0 is the initial velocity (when t = 0 )
H_0 is the initial height (when t = 0)
In this problem we have
substitute the given values
Rewrite

Answer:
Correct (1,9), (2,14)
Incorrect (1,8),(2,13)
Step-by-step explanation:
It is simple.
To find the correct values plug a x value.
For Example;
X=1
y=5(1)+4
y=5+4
y=9
so your X value is 1 and your Y value is 9
To solve for the incorrect values
Find the correct values and subtract 1 form the Y value.
Answer:
Step-by-step explanation:
You didn't mark your graph but I'm assuming the point is (1,2)
You notice how the function stops at the point? x and y can not be above that point because there is no line above it.
The domain of the function means what can x possibly be.
The maximum value of x in this function is 1 because that's the x value of the point where the function ended. This means x can at most be one or x≤1. So the domain is x≤1.
The range of the function means what can y possibly be.
The maximum value of y in this function is 2 because that's the y value of the point where the function ended. This means y can at most be two or y≤2. So the range is y≤2.
