Step-by-step explanation:
Answer:
Extrapolation
Step-by-step explanation:
Given the data:
Distance (mi): 2 2.5 3 3.5 4
Time (min): 23 28 34 34 40
Line of best fit for the data:
y = 8x + 8
Making use of the best fit equation to make prediction of time is an example of extrapolation. This is because our result will be based in the fact that further prediction of the time it takes for any predicted distance will follow the same trend. Hence, it is important to note that a best fit line or regression model uses extrapolation techniques to make predictions.
Hence,
For the above ; estimate for X =5 will be ;
y = 8(5) + 8
y = 40 + 8
y = 48 minutes
Answer:
1) x≠7
2) x≠3 or -7
Step-by-step explanation:
1. The given function is
![f(x) = \frac{1}{x - 7}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20%5Cfrac%7B1%7D%7Bx%20-%207%7D%20)
This function is undefined if the denominator is equal to zero .
Therefore the restriction is that:
The denominator is not zero.
![x - 7 \ne0](https://tex.z-dn.net/?f=x%20-%207%20%5Cne0)
![x \ne7](https://tex.z-dn.net/?f=x%20%5Cne7)
2) Assuming the second function is
![f(x) = \frac{(x + 7)(x - 9)}{(x - 3)(x + 7)}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20%5Cfrac%7B%28x%20%2B%207%29%28x%20-%209%29%7D%7B%28x%20-%203%29%28x%20%2B%207%29%7D%20)
This function is not defined when the denominator is zero.
This implies that:
![(x - 3)(x + 7) \ne0](https://tex.z-dn.net/?f=%28x%20-%203%29%28x%20%2B%207%29%20%5Cne0)
The restrictions are:
![x \ne3 \: or \: - 7](https://tex.z-dn.net/?f=x%20%5Cne3%20%5C%3A%20or%20%5C%3A%20%20-%207)

the answer is B
