Answer:
D. 4X^2+1
Step-by-step explanation:
This is because when you add one after the function it moves it up one unit. When you multiply the first part by four, it causes the function to vertically stretch making it narrower.
Hm good question. Maybe you can measure the temperature in a place and measure another temperature in a other place and add it together.

Answer:
y = f(x-2) + 1
Step-by-step explanation:
The original functions looks like f(x) = |x|
For the new function the vertex has shifted -2 left (x) and up +1 (y)
So
y = f(x-2) + 1
If we fit the data as calories as a function of wt loss/week, we need to arrange the data first from lowest to highest wt loss/week lbs and calories. Then, the set of points can be plotted in a graph and a graphical method of line fitting can be used. Curve fitting programs (which are also in the calculator) can be used. The result is:
y = -266.5741x + 2246.5116
The value of R² is 0.7109. The fit is not very good since R² is quite far from 0.99.
