hi
do you know what the domain and range refer to?

adajiamcneal · Answer

no idea

surry99 · Answer

ok for a graph of y vs x which is what you have, the domain refers to the permissible values of x and the range refers to the permissible values of y

adajiamcneal · Answer

wait so how do i find them?

adajiamcneal · Answer

@surry99

surry99 · Answer

ok look at your graph and tell me what is teh lowest value of x possible

adajiamcneal · Answer

would it be 2?

surry99 · Answer

not quite look a little more carefully

adajiamcneal · Answer

im confused..

surry99 · Answer

ok can you see how how as the graph approaches x=1, the values of y go up very quickly?

adajiamcneal · Answer

yeah but it never actually hits 1

surry99 · Answer

exactly, that part of the graph is called an asymptote. So the values of x are always greater than 1 but never equal 1.  So the domain would be x>1

adajiamcneal · Answer

ohhhh i see i see :)

surry99 · Answer

See how the x values are always bigger than 1?

surry99 · Answer

Great....now taek a look at the permissible values for y

surry99 · Answer

What is y always greater than in the graph?

adajiamcneal · Answer

5?

surry99 · Answer

not quite...can you see the y values are always greater than zero but never equal 0?

adajiamcneal · Answer

yeah i see that

surry99 · Answer

so the domain (permissible values for x) is x> 1
the range (permissible values for y) is y >0.
Make sense?
