See below for the domain and the range of the functions.
<h3>How to determine the domain and the range?</h3>
As a general rule, all linear functions have a domain and a range of all set of real numbers i.e. (−∞, ∞)
The functions (2), (3), (4), (5) and (6) are linear functions.
So, their domain and range are (−∞,∞)
For function (1), we have:
f(x) = 3(3)^x - 1
The above is an exponential function.
The domain of an exponential function is all set of real numbers i.e. (−∞, ∞)

The answer to question 1 is 120 times. and the answer to question 2 is 60% probability.
hope this helps:)
Answer: Positive
Step-by-step explanation:
A scatter plot for speed and distance is created.
We know that distance = speed x time
Hence when speed increases , distance increases and similarly when speed decreases, distance decreases.
Thus if we plot on x axis distance, we find that x increases when y increases.
So we find that there is a strong positive relationship between the two variable
D=tS
where D= distance S=speed and T=time.
Since D varies directly as speed, we have positive relationship.
Hope this helps! :)
