Question

Which of the following are true?
A) The graph of f(x)= 1/2 sqrt of X will look like the graph of f(x)= sqrt of x but will streth it vertically by a factor of 2.
B) The graph of f(x)=1/2 sqrt X will look like the graph of f(x)= sqrt of X but will shrink it horizontally by a factor of 1/2
C) f(x)= 1/2 sqrt X has the same domain and range as f(x)= sqrt of X
D) The graph of f(x)= 1/2 sqrt X will look like the graph of f(x)= sqrt X but it will shrink it vertically by a factor of 1/2

BTW multiple answers are correct.

Answer 1

Do you have the graph? or is it just a question?

Answer 2

Just a general question

Answer 3

It might be helpful to graph these though

Answer 4

yes it would be very helpful

Answer 5

well they both look pretty similar when graphed, I just graphed them on my calculator

Answer 6

It looks like domain for both are (0,infinity)

Answer 7

Okay I did too, so then if it is by 1/2 it will shrink the graph vertically. This should help you

Answer 8

If it is by two it will grow

Answer 9

Okay so then one of the answers is that the f(x)=1/2 will shrink the graph vertically compared to the graph of f(x)= sqrt of X

Answer 10

But the graph containing 1/2 will shrink the graph vertically by 1/2? right??

Answer 11

yes.. you are right.. I have to go if you are still having trouble i will try and help you just message me :)

Answer 12

Okay
