Answer: (C) y= x − 2
Explanation:
y=x-2 is the choice that satisfies all the points in the table. This can be verified case by case:
y=x-2
(-3,-5): -5 = -3 -3
(-1,-3): -3 = -1 - 2
(1,-1): -1 = 1 - 2
(3, 1): 1 = x - 2
(5,3): 3 = 5 - 3
The time it will take the thermometer to hit the ground is 22 seconds
<h3>Calculating Time </h3>
From the question, we are to determine the how long it would take the thermometer to hit the ground
From the given information,
The equation for the height as a function of time is
h(t) = -16t² + initial height
From the given information,
The thermometer falls from a weather balloon at a height of 7744 ft
∴ Initial height = 7744 ft
When the thermometer hits the ground, h(t) = 0
Thus, we get
0 = -16t² + 7744
16t² = 7744
t² = 7744/16
t² = 484
t = √484
t = 22 seconds
Hence, the time it will take the thermometer to hit the ground is 22 seconds

For this case we have the following table:
x f(x)
<span><span><span>0 2
</span><span>1 5
</span><span>2 10
</span><span>3 17
</span></span></span> The equation that best fits the data in the table, for this case, is given by a quadratic function.
<span><span><span> </span></span></span>The quadratic function in its standard form is:
f (x) = x2 + 2x + 2
Answer:
f (x) = x2 + 2x + 2
