Let x be the price of the blouse.
42=2x-14
56=2x
28=x
The blouse was $28
Answer:
f(x) is linear
g(x) is exponential
Step-by-step explanation:
A linear function will always have the same rate of change between equally distant points, while an exponential function will have an increasingly large rate of change between equally distant points.
First, look at f(x). All these points are equally distant at 2 units apart on the x-axis, so they can be directly compared:

All of these points are the same distance apart on the y, so f(x) must be a linear function.
Now look at g(x). These are also all equally distant at only 1 unit apart.

These are very clearly not the same distance apart on the y, so g(x) must be the exponential function.
Answer:
4. It should be less than coefficient on str in the first regression
Step-by-step explanation:
Since the str and income are positively correlated and the coefficient on income in the second regression is positive, the coefficient on str in the second regression therefore should be less than coefficient on str in the first regression.
