ANSWER
Option D
EXPLANATION
The parent radical function is
The transformed function is
This is a transformation of the form.
which shifts the parent function horizontally by k units to the right and stretches the parent function vertically by a factor of 'a'.
In this case a=2 and k=3,
there is a horizontal shift of 3 units to the right and a vertical stretch by a factor of 2.
The last choice is correct.
What is the domain and the range of the relation represented by the ordered pairs? {(6,6),(−1,3),(3,6),(0,4)}{(6,6),(−1,3),(3,6)

Hello,
Let's review: The domain is all the possible x values of a relation/function. To get the domain, we look at the x values in the ordered pairs.
The domains are: {-1, 0, 3, 6} - as you can see these are the x values of each pair.
Let's review: The range is all the possible y values in a relation/function. To find the rang, we look at the y values of the pairs.
The ranges are: {3, 4, 6} - notice how there are two "6" in those pairs, and when writing the range, you don't need to repeat the number if it's already written.
I hope this helps! =)

The correct answer is 3W n W i believe
Answer:
270 miles
Step-by-step explanation:
We know the formula for distance
d = rt where r is the rate and t is the time
d = 90 mph * 3 hours
d = 270 miles
Answer:
No, Mr. Hernandez’s sample is random, not biased, large enough compared to the population, but 28 is not 20% of 90.
Step-by-step explanation:
At Lawson Middle School, Mr. Hernandez asked 90 randomly selected students from each grade level for their favorite subject.
90 randomly selected students from each grade level for their favorite subject, and 28 chose social studies as their favorite.
so, the percent of students who love social studies is given by:
28/90 x 100=31.11%
He used this data to draw the inference that out of the 250 middle school students, about 20% prefer social studies.
No, Mr. Hernandez’s sample is random, not biased, large enough compared to the population, but 28 is not 20% of 90.
