What is the domain of f(x) = -(x-6)^2-30
1 answer:
Answer:
(-∞, ∞)
Step-by-step explanation:
To find the domain, we find how far along the x axis the line goes.
Specifically, we're looking for when x <em>doesn't</em> exist, because that's much easier.
So we're looking for when x is undefined. In order to have something undefined, you need the , or
.
As we can see, there's no part where x is undefined. Therefore, the domain is
(-∞, ∞)

Based on the information given, the true statement true about their gas-price data is A. Raquel’s data are most likely closer to $3.42 than Van’s data are to $3.78.
<h3>Solution to the gas-price data.</h3>It should be noted that a standard deviation simply measures how dispersed the data will be in relation to the mean.
From the complete question, the mean of Raquel's data is given as 3.42 while the standard deviation is given as 0.07. On the other hand, the mean of Van's data is given as 3.78 while the standard deviation is given as 0.23.
Therefore, it can be deduced that Raquel’s data are most likely closer to $3.42 than Van’s data are to $3.78.
