what?

- Anikate

i dont get it

- Anikate

keep goig i'l try to figure it out

- anonymous

There are no restrictions to the range

- Anikate

um... need to find range is all i no

- anonymous

Okay, well you could always substitute 0 for the x value and work out the whole question from there. However, the answer I gave you earlier should be correct

- Anikate

what was the answer u gave earlier?

- Anikate

-3.5?

- anonymous

All real numbers. The domain would be all real numbers, and so should the range

- Anikate

what r real numbers?

- anonymous

Or, you could set y= 0 and work out the whole equation

- Anikate

then what would be my answer?

- Anikate

-3.5?

- anonymous

For instance,
(0= 2x - 7/ 2 ) x 2
0= 4x-14
14=4x
14/4=x

- anonymous

That's solving for x

- Anikate

range is always y right?

- anonymous

Substitution with x and zero would look like this:
y= 2(0) -7/2
y= -5/2

- anonymous

that is the range when solving the equation

- Anikate

actually it would be -3.5

- anonymous

Well, if you were trying to be precise, then yes. However, most math classes perfer that you leave it in the fractional form.

- Anikate

idk the range when soling equatyion. and i know

- anonymous

also it should be -2.5, not -3.5

- Anikate

how
?

- anonymous

2-7 = -5
-5 divided by 2 = -2.5

- Anikate

y=2(0)-7/2
y=0-7/2
y=-3.5

- anonymous

oh, I just got served! You are absolutely right my dear. Thanks for catching my mistake ;}

- Anikate

oh it's k np

- anonymous

So, do you have your answer?

- Anikate

-3.5?

- anonymous

yes

- Anikate

yup thx :D

- anonymous
