Question

Which of the following are true statements?

Check all that apply.

A. The graph of ƒ(x)=-1/2√x will look like the graph of ƒ(x)=√x but will reflect it about the x-axis and shrink it vertically by a factor of 1/2.
B. The graph of ƒ(x)=-1/2√x will look like the graph of ƒ(x)=√x but will shrink it horizontally by a factor of 1/2.
C. ƒ(x)=-1/2√x has the same domain but a different range as ƒ(x)=√x.
D. The graph of ƒ(x)=-1/2√x will look like the graph of ƒ(x)=√x but will shrink it vertically by a factor of 1/2.

Answer 1

what do you think?

Answer 2

A and B.. but thats prob completly wrong. thats why im asking here. lol

Answer 3

not b C

Answer 4

well it is A because the neg sign means the graph will be below the x-axis thus reflected.
Its not B because it doesn't mention a reflection.
Not D because of same reason.
It is also C because the y_values change but the x_values remain the same

Answer 5

oh so i was right. thanks!

Answer 6

no problem
