DO NOT GIVE ANSWER! I just need an explanation. match with range.

Oh, thank you so much, and links are not preferred but o. k.
Brainliest to whoever explains more, and thanks

Hi there!

The range of a function describes its possible y-values. For example, y=x produces a linear graph. Its range is all real numbers, meaning that for any value of y, the function is defined.

However, for y=x², for example, the range is y>0, since there the graph doesn't travel to y-values less than 0. The function is only defined when y>0.

To find the range of the given functions, you can try graphing them. Or, if you've memorized the ranges of their parent functions, you can try to take that and apply transformations.

Answer for the first question:

f(x)=-√x

The parent function is f(x)=√x. The range of this is y≥0.

f(x)=-√x

Adding a negative in front of the square root reflects the function across the x-axis, meaning the range is therefore flipped too:

y≤0

I hope this helps!

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

answer: 40.95
